Abstract

A particle mass concentration in an aerosol volume can be detected by an optical particle sensor. In order to ensure that different degrees of contamination of the optical particle sensor can be detected by the sensor and can be taken into consideration, the optical particle sensor identifies individual particles at low particle concentrations of up to 1000 particle s/cm3.
