Fast Automotive Particle Emission Sprectrometer (FAPES)
The Fast Automotive Particle Emission Sprectrometer (FAPES) can be used to carry out rapid measurements of particles produced during combustion processes. A bipolar charger is used, which establishes a defined equilibrium charge distribution on the particles. The charged particles are classified using twelve Differential Mobility Analyzers (DMAs) operated in parallel. Precise detection of the particle charge is carried out using twelve Faraday Cup Electrometers (FCE), which are characterized by a low noise level and a fast response time, which is crucial for the overall system. The particle charge is detected in the FCE by spatial separation from the electric fields in the aerosol classifier.

Portable Aerosol Spectrometer
The Aerosol Dust Monitor & Counter 1.108 is a dust measuring device for measuring dust in the air and its aerosol distribution. The system is used in the areas of occupational safety, environmental measurement, filter and air quality control. A semiconductor laser, which serves as a light source, is used to measure the scattered light of the individual particles. The 90° scattered light is directed onto the receiver diode via a mirror with an opening angle of 60°, whereby a light pulse is emitted when each particle passes over it. The signals are classified according to the amplification.
Technical Data

| Particle concentrations | up to 2.000.000 Partikel/Liter |
| Measuring intervals | 6 s/ 1, 5, 10, 30 or 60 min |
| Signal amplification | 0,3 bis >20µm in µg/m³ |
Gasmet DX4000
The FTIR gas analyzer Gasmet DX4000 is used for emission monitoring, comparative measurements or the control of catalytic processes, whereby several gas components in hot and moist samples can be precisely monitored. The corrosion-resistant measuring cell can be heated up to 180 °C to ensure that the sample remains in the gaseous phase at high concentrations of H2O or corrosive gases.
