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

production on order

Low pressure cascade impactors are designed for a particle size related sampling of ambient and industrial aerosols. Depending on the analysis method, e.g. gravimetry, SEM-EDS, PIXE, ICP-MS/AES, TGA, XRF/IBA, the weight or mass size distributions as well as the size distributions of elements and compounds can be determined.

For particle separation several materials can be used, e.g. thin foils made of aluminum, polyvinyl fluoride (PVF / TEDLAR®), polytetrafluoroethylene (PTFE / TEFLON®), polycarbonate (PC / KAPTON®), hydrophilic polypropylene (PP) or special materials as silicon wafer as well as special treated quartz fibre back-up filters.

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.

  • Application-oriented flow rates from 5 l/min up to 60 l/min and cut-offs from 20.0 µm down to 1 nm
  • Loss-minimizing flow design and optional anti-electrostatic charge bypass
  • Pre-separator and optional back-up filter stage
  • High-precision calibration of each impactor with protocol once after manufacturing
  • Calibration-free high-precision flow rate regulation
  • All impactor parts - except the gaskets - are made of high-grade acid-proof steel
  • Special gasket sets, pre-separator greases, connecting tubes and heating jackets for an upgrade to operating temperature ranges from -50/-30 °C up to +180/+310 °C
  • Isokinetic inlets, special sampling probes, sampling lances/flanges and nozzle sets manufactured of non-corrosive high-grade acid-proof steel
  • Cleaning sets for an intensive but mild maintenance of the impactor parts and the fine nozzles
  • Matching vacuum pumps and closed vacuum pump stations with stainless steel housings
  • New: microprocessor-controlled vacuum pump stations for an automated operation, a complete data recording and full documentation of the samplings incl. optional calculation and continuously accumulation of the dry standard volume for an accurate comparison of the mass concentrations/analyses from different sampling sites
  • Meteorological sensor packages: temperature, pressure, relative humidity, wind, precipitation, sun (global) radiation, UV radiation, radioactivity, noise, vibration (now up to 4 sensor packages per device with plug&play )
  • Inspection service and corrective maintenance by modular replacements (ISAP® '4 screws - 5 minutes' principle)

Mobile Wind Solar Hybrid Energy Supply Systems ISAP® WSH

production on 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 worked without any 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.
