Description of TOPAS LAP 340/L

Using the LAP 340/L single particle scattered light counter, low-concentration aerosols – gaseous samples containing gas-borne particles – are analysed in terms of particle number and size.

Optical particle counters are used for quality control in filter production and optimisation. The requirements for the measuring instrument arise mostly from the applied standards and directives. The particle counter is characterised by a wide measuring range (0,2 … 10 µm) and a high measuring volume flow of 2,83 l/min. Compared to aerosol spectrometers, the LAP 340/L enables efficient analysis of large sample volumes. The particle counter is designed for stationary and mobile use.

For testing gaseous samples with particles, the measuring device sucks in a sampling volume flow of 2,83 l/min via an internal pump. The entire sample is fed into the measuring cell and exposed to light from a laser diode. A photodetector detects the light scattered by the particles. The signals are processed and classified into different classes according to the pulse height. A calibration function is used to correlate the pulse height classes to the respective particle size. Based on the number of signals, the number of particles in the examined sample is determined.
