Automated Low Volume Aerosol Sampling Devices ISAP® 1050e and ISAP® 1050r (Small Filter Devices)

Current production type / capacity: Series / approx. 40 Devices per month
Current delivery periods basic devices with standard accessory incl. one-week burn-in and final testings: approx. within 8 weeks from order
The devices and the communication / operation software are checked / free from US/UN/EU Dual-Use export restrictions at present
ISAP® 1050e basic devices sometimes as rental or refurbished

The microprocessor controlled Aerosol Sampling Devices ISAP® 1050e and ISAP® 1050r are designed for the determination of airborne homogenously dispersed suspended matter (aerosols), which are agglomerated fine dust particles of different composition, mainly emitted by urban and industrial sources as machines, vehicles or combustions. Defined air volumes are sucked through sampling heads (inlets), in which the aerosols are deposited accumulatively on foils, filters or in polymer foams. With the subsequent laboratory works the mass concentration of the aerosols and of their health-related components, such as heavy metals, their compounds and complexed chlorohydrocarbons, can be determined by differential weighing of the filters and by chemical / physical analysis of the sampled material.

The main field of application is the measuring of dust immission with aerodynamic diameters smaller than 30 µm. The flow rate is 2.3 m3/h and thus, the ISAP® 1050e/r are considered to be 'Low Volume Sampler' (LVS or so-called 'Small Filter Devices').

Both device types are reference / standard sampling devices for the determination of the mass concentration of total suspended particulates (TSP) acc. to VDI 2463 P. 1+7+8, of the size-fractioned particulate matter (PM10 / PM2.5) acc. to EN 12341:2014 / former EN 14907 and its element analysis as per EN 14902 and VDI 2267 P. 1 et seq. as well as for pentachlorophenol / gamma-hexachlorocyclohexane (PCP / Lindan acc. to VDI 4301 P. 2). The devices are also conform to the European and German directives and standards relating to the limit values and to the basis requirements of the equipment design for air quality monitoring according to 2008/50/EG, 39. BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.

Since 1999 the ISAP® 1050 series is listed as commercial reference sampler by the Chemical Coordinating Centre (CCC) of the European Monitoring and Evaluation Program (EMEP), the Norsk institutt for luftforskning (Norwegian Institute for Air Research NILU) and by the Global Atmosphere Watch (GAW) of the World Meteorological Organization (WMO).

The type extension 'e' stands for an extended device version with the full range of accessory. For the different sampling, evaluation and analysis methods there are diverse inlets, sampling tubes and compatible collecting sets available. Beside the single stage inlets for TSP or PM and the combined inlet for TSP and PCP / Lindan, the multistage inlets collect several PM fractions within one single sampling. The collection sets comprise ring foils, round filters, protection gauze and foam cylinders made of different materials as aluminum, glass microfiber or quartz microfiber, polyimide (KAPTON®), polycarbonate (PC), polyester, polypropylene (PP), polytetraflouroethylene (PTFE - TEFLON®), polyurethane foam (PU) or polyvinyl fluoride (PVF - TEDLAR®).
A high power pump module enables samplings with high flow resistance (back-up) filters e.g. of PC or PTFE, which are most useful for pure optical evaluation methods as Scanning Electron Microscopy (SEM) or for atomic spectroscopic trace element analysis of Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu, Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn with Atomic Absorption Spectroscopy (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Photon-Induced X-ray Emission (PIXE) or Total Reflecting X-ray Fluorescence Spectrometry (TXRF).

With the ISAP® 1050e a large number of meteorological and application orientated sensor packages enable the documentation of the environmental conditions at the samplings as well as diverse causal correlations at evaluation.
For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages available.

The type extension 'r' stands for a function-reduced device version with a reduced range of accessory. The ISAP ® 1050r was designed for getting started with directive-conform routine samplings with priceless glass microfiber or quartz microfiber filters. In case of a later necessity for more features the ISAP® 1050r can be upgraded to the full functionality of the 'e' version by a modular conversion kit.

The devices are applicable for outdoor and for indoor measurements.

Fully Automated Low Volume Aerosol Sampling Device ISAP® 1050-31e (Small Filter Device) with sequential filter changer

Current production type / capacity: Series / approx. 4 Devices per month
Delivery periods basic devices with standard accessory incl. one-week burn-in and final testings: approx. within 3 month from order

The microprocessor controlled aerosol sampling device ISAP® 1050-31e is designed for the determination of airborne homogenously dispersed suspended matter (aerosols), which are agglomerated fine dust particles of different composition, mainly emitted by urban and industrial sources as machines, vehicles or combustions. Defined air volumes are sucked through a sampling head (inlet) and the aerosols are deposited accumulatively in the down-stream filter changer. With the subsequent laboratory works the mass concentration of the aerosols and of their health-related components, such as heavy metals, can be determined by differential weighing of the filters and by chemical / physical analysis of the sampled material.

The main field of application is the measuring of dust immission with aerodynamic diameters smaller than 30 µm. The flow rate is 2.3 m3/h and thus, the ISAP ® 1050-31e is considered to be a 'Low Volume Sampler' (LVS or so-called 'Small Filter Devices').

BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.

Since 2002 the ISAP® 1050-31 series is listed as commercial reference sampler by the Chemical Coordinating Centre (CCC) of the European Monitoring and Evaluation Program (EMEP), the Norsk institutt for luftforskning (Norwegian Institute for Air Research NILU) and by the Global Atmosphere Watch (GAW) of the World Meteorological Organization (WMO).

The type extension '31e' stands for an extended device version with filter changer and extensive accessory. The device allows a fully automated time-scheduled sequential filter change for up to 31 days for a '24 h monitoring'. A filter magazine can contain up to 31 filter holders or 15 filter holders and 16 separators. The separators can be used to close the air space above and below the loaded filters, so that the samples cannot evaporate or interact. As closed units, the filter magazines can be changed most easy and contamination-free. The separate, optional thermostated filter housing section reduces losses of semi-volatile compounds from the stored loaded filters on higher environmental temperatures.

For the different sampling, evaluation and analysis methods there are diverse inlets for TSP or PM and compatible collecting sets available. The collection sets comprise round filters and protection gauze made of glass microfiber or quartz microfiber, polypropylene (PP), polycarbonate (PC), polyester or polytetraflouroethylene (PTFE - TEFLON®).

High Volume Aerosol Sampling Devices



 

Developing: Fully Automated Low Volume Aerosol Sampling Devices ISAP® 2150-31e

compact with sequential filter changer and closed filter magazines for a total monthly monitoring - coming here soon.



 

Fully Automated High Volume Aerosol Sampling Device ISAP® 3000-31es (scientific) with universal filter changer

Current production type / capacity: Manually on order / -
Delivery periods application-oriented basic devices with standard accessory incl. one-week burn-in and final testings: approx. within 6 month from order

The microprocessor controlled aerosol sampling device ISAP®3000-31es is designed for the determination of airborne homogenously dispersed suspended matter (aerosols), which are agglomerated fine dust particles of different composition, mainly emitted by urban and industrial sources as machines, vehicles or combustions. Defined air volumes are sucked through a sampling head (inlet) and the aerosols are deposited accumulatively in the downstream filter changer. With the subsequent laboratory works the mass concentration of the aerosols or of their health-related components, such as heavy metals, can be determined by differential weighing of the filters or by chemical / physical analysis of the sampled material.

The main field of application is the measuring of dust immission with aerodynamic diameters smaller than 30 µm. The flow rate is 30.0 or 68.0 m3/h and thus, the ISAP® 3000-31es is considered to be a 'High Volume Sampler' (HVS).

The device is reference sampling device for the determination of the mass concentrations of total suspended particulates (TSP) acc. to VDI 2463 P. 1 as well as of the size-fractioned particulate matter (PM10 / PM2.5) acc. to EN 12341:2014, former EN 14907 and its element analysis as per EN 14902 and VDI 2267 P. 1 et seq.

The device is also conform to the European and German directives and standards relating to the limit values and to the basis requirements of the equipment design for air quality monitoring acc. to 2008/50/EG, 39. BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.
Since 1999 the ISAP® 2000/3000 series is listed as commercial standard sampler by the Chemical Coordinating Centre (CCC) of the European Monitoring and Evaluation Program (EMEP), the Norsk institutt for luftforskning (Norwegian Institute for Air Research NILU) and by the Global Atmosphere Watch (GAW) of the World Meteorological Organization (WMO).

The type extension '31-es' stands for an extended device version with filter changer and large range of scientific relevant features and accessory. Thus, the device allows electively a fully automated time-scheduled sequential filter change for up to 31 days at '24h monitoring' or a fully automated direct event-induced filter change. This 'Event mode' allows samplings to attain significant information regarding the sources of the aerosol, the transport mechanisms in the air and the input mechanisms from the air to bordering media - so, depending on a number of relevant criteria, such as wind direction and wind velocity, precipitation, relative humidity, or radioactivity or combinations of these parameters, the designated filters are moved into the air flow. The multiple use of the same filter (group) on identical event parameter configurations ensures a maximum work period of the filter magazine and a minimization of blank value problems at analyzing.
A filter magazine contains 31 carriers for standard filter holders or 15 carriers for (multi-stage) impactor filter holders. As modular unit the filter magazine can be changed easy and contamination-free. The separate, optional thermostated filter housing section reduces losses of volatile compounds from the stored loaded filters on higher environmental temperatures.

For the different sampling, evaluation and analysis methods there are diverse inlets, single- and multi-stage impactor filter holders as well as adequate collecting sets available. The collecting sets comprise round filters, slotted foils and protection gauze made of different materials as aluminum, glass or quartz microfiber, polypropylene (PP), polycarbonate (PC), polyester, polytetraflouroethylene (PTFE - TEFLON®) or polyvinyl fluoride (PVF - TEDLAR®).
The High power pump module enables samplings with high flow resistance filters e.g. of PC or PTFE, which are most useful for pure optical evaluation methods as Scanning Electron Microscopy (SEM) or for atomic spectroscopic trace element analysis of Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu, Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn with Atomic Absorption Spectroscopy (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Photon-Induced X-ray Emission (PIXE) or Total Reflecting X-ray Fluorescence Spectrometry (TXRF).

A large number of meteorological sensor packages enables differential correlations between the measured mass concentrations or the element analyses with the environmental sampling conditions.
For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages available.

The device is applicable for outdoor measurements only and is completely maintenance-free for at least seven years operation at an average of one filter change per day.

Financial support for the development of the precursor prototype ISAP®2000 was provided under contract no. 03F0058A by the German Federal Ministry of Research and Technology.

The main field of application is the measuring of dust immission with aerodynamic diameters smaller than 100 µm with radioactively compounds. The flow rate is up to 1,000 m3/h and thus, the ISAP® 4000e is considered to be 'Ultra High Volume Sampler' (UHVS). Due to the high flow rate the device is predestinated for the determination of the mass concentrations of radioactively aerosol compounds.

The device is conform to the European and German directives and standards relating to the limit values and to the basis requirements of the equipment design for health-related air quality monitoring acc. to 2008/50/EG, 39. BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.

Low Pressure Cascade Impactors



Automated Standard/High/Low Temperature Low Pressure Cascade Impactors ISAP® LPCI, ISAP® HT-LPCI and ISAP® LT-LPCI
and accessories for measuring micro and nano particles

Current production type / capacity: Series / approx. 10 Systems per month
Delivery periods basic systems with standard accessory incl. one-week burn-in and final testings: approx. within 6 weeks from order
ISAP® LPCI standard basic devices sometimes as rental or refurbished

Low pressure cascade impactors ISAP® LPCI are designed for the determination of dispersed airborne particles (aerosols) in pipe flows or pipe outlets or in ambient air. Aerosols are agglomerated fine dust particles of different composition, mainly emitted by urban and industrial sources as machines, vehicles or combustions. Defined air volumes are sucked through the impactor stages and the aerosols are deposited accumulatively size selective on thin foil material or on special material as silicon wafers as well as on special treated quartz microfiber filters. With the subsequent laboratory works the mass concentration of the aerosols and of their health-related components, such as heavy metals or their compounds, can be determined by differential weighing of the foils and filters and by chemical / physical analysis of the sampled material as per EN 14902 and VDI 2267 P. 1 et seq.

The main field of application is the measuring of dust immission and emission with aerodynamic diameters smaller than 20 µm. Application-oriented special designs have flow rates from 5 l/min up to 60 l/min and cut-offs from 20.0 µm down to 1 nm. The necessary minimum absolute pressure is 20 hPa (0.0032 psi).

The flow rate controlling by a critical nozzle, a lossless flow system and optimized Reynolds numbers ensure correct and sharp cut-offs, which are documented by the high-precisely calibration of each impactor after production.

For the different sampling, evaluation and analysis methods there are diverse isokinetic inlets, special sampling probes, sampling lances/flanges as well as compatible collection sets available. The collection sets are made of different materials as aluminum, polyimide (KAPTON®), polycarbonate (PC), polyester, polypropylene (PP), polytetraflouroethylene (PTFE - TEFLON®), polyvinyl fluoride (PVF - TEDLAR®) or special materials as silicon wafer as well as special treated quartz fiber back-up filters.

Beside the pure gravimetric determination of the aerosol mass concentrations by weighing and pure optical methods as Scanning Electron Microscopy (SEM), there are several established chemical / physical evaluation and analytic methods for quantitative trace element determination of e.g. Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu, Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn by atomic spectroscopic methods as Atomic Absorption Spectroscopy (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Photon-Induced X-ray Emission (PIXE) or Total Reflecting X-ray Fluorescence Spectrometry (TXRF).

The High and Low Temperature Low-Pressure Cascade Impactors ISAP® HT-LPCI, ISAP® LT-LPCI have special gaskets and allow samplings from media with temperatures of -50 up to +310 C. Standard impactors can be upgraded with High or Low temperature gasket sets for the use with aforesaid media temperatures.

An automated operation is given by the use of the optional pump station ISAP® LPCI-PSe. The type extension 'e' stands for an extended pump station with a microprocessor electronic unit, which allows the use of more accessory as well as automated samplings and a comfortable evaluation under inclusion of the environmental parameters at sampling site: An impactor temperature sensor and a large number of meteorological and application orientated sensor packages enable differential statements about the causal correlations of the determined mass concentrations and the element analysis with the environmental conditions at the samplings.
For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages for the pump station available.

Developing: with the ISAP® (HT-)LPCIa the new nozzle geometry from the current nano technology science will be realized. Together with the optimized Reynolds numbers of each stage this results in very sharp cut-offs.

Mobile Wind Solar Hybrid Energy Supply Systems ISAP® WSH

Current production type / capacity: Manually on order / -
Delivery periods application-oriented basic systems with standard accessory incl. one-week burn-in and final testings: approx. within 6 month from order

The mobile wind solar hybrid energy supply systems ISAP® WSH allow the operation of our power consumption reduced low-volume aerosol sampling devices ISAP® 1050eWSH and ISAP® 1050-31eWSH on sampling sites without any mains supply and also if a diesel generator set is unpreferred.

The self-sufficient energy supply systems consist of a wind generator, two photovoltaic module groups and one accumulator station. The system performance is adjusted in the planning through the choice of the wind generator and the variation of the amount of photovoltaic modules to the typical regional wind and insolation conditions of the intended measuring sites.

If additional energy should be required due to poor environment conditions on site, two additional photovoltaic modules can be mounted on the spare places of the module group carrier frames.

With the interval function "time spans" our low-volume samplers can also provide results in light wind and low sunshine periods by operation alternating, i.e. with sampling intermissions. The progress of wind strength and insolation can be gathered by the optional meteorological sensors.

In order to be able to transport the systems easy and cost-efficient to different measuring sites, the components are modular, i.e. as far as reasonable dismountable.

Application-oriented special devices and sampler components

production on order

Besides our standard devices we also deliver customer-specific samplers and sampler components, e.g. inlets, pump units and flow rate controller.

Example: application-oriented special devices for aerosol samplings in polar regions

In polar regions the devices are exposed to extremely low temperatures down to -65 C, snow storms and high altitudes up to 3000 m above sea level in the Antarctic.

This requires special features of devices and accessory against freezing and condensation - range from auxiliary heatings over insulations up to special lowest temperature electronic elements and feed lines.

The special inlets must be protected against snow entry which has to be effective on horizontal strong winds and against giant snow drifts.

Quotation order Inlet design



Due to the very high effort in logistic for device applications in polar regions, subsequent improvements are excluded - there is only one try.

We are glad that our intensiv planning was successful and that the devices still work without relevant problems.

Example: application-oriented sampler units and wind-driven control units for aerosol samplings on research vessels

For aerosol sampling on research vessels it is important to avoid the suck in of the exhaust fumes of the vessel. The control units automatically switch off the sampling if the wind blows from the vessel chimney towards the sampling device and also if the wind velocity is lower than a preallocated minimum threshold value to avoid a contamination through undefined movement.

The initialisation of the control unit is easily done by a PC communication surface: Here, the sampling parameters as forbidden wind sector and the minimum threshold value of the wind velocity as well as the delay time for the automatic restart can be altered.

To enable a complete and comfortable evaluation of the sampling, the wind parameters, the compass course of the vessel and the device operation times are recorded and edited for an export to spreadsheet programmes.

The very special conditions on a research vessel are the high salt concentrations in air and sea spray, the abruptly movements of the ship and massive floodings over the working deck.


This requires special features of devices and accessory against corrosion, damages due to movements and the entry of sea water - range from housings made of special high-alloyed steel, over shock-absorbing holders for pumps and electronics to sea water-resistant connectors and feed lines.

As a separate service we calculate and draw you an application-oriented TSP or PM single- or multistage inlet for the extension of your system:

Example: wind-driven control unit for the analysis of the pollutant gas components in ambient air on research vessels

The control unit allows the automated analysis of the ambient sea air on winds in a major wind sector. It is possible to switch up to 4 gas analyzers in an analysis mode or in a zero air mode.

The analysis mode is active only if the wind direction is in the pre-allocated sector and if the wind velocity is higher then a preallocated minimum threshold value. In all other cases the zero air mode is active and the gas analysers receive clean bottle gas.
