AEROSOL PARTICLE MEASURING DEVICE FOR DETERMINING MATERIALS IN REAL TIME BY MEANS OF FLUORESCENCE LIFETIME MEASUREMENT IN THE FREQUENCY RANGE

摘要

The present invention relates to an aerosol particle measuring device (20) for the qualitative and/or quantitative determination of fluorescent materials (2) in real time by means of fluorescence lifetime in the frequency range, comprising at least one measuring device (1) with light source (3), detector (4) and measuring chamber (8), an aerosol inlet (21), an aerosol outlet (22) and an air flow generation and control device with electronics (23), wherein the detector (4) is a semiconductor technology-based electronic photon detector for light detection, in particular a silicon photomultiplier (SiPM). Also claimed are a method for the qualitative and/or quantitative determination of fluorescent materials (2) in real time by means of fluorescence lifetime measurement using the aerosol particle measuring device (20) and the use of the aerosol particle measuring device (20) and/or of the method.
