Method and device for quantitative and qualitative on-line differentiation of biotic and abiotic particles

Abstract

The invention relates to a method and a device for quantitative and qualitative on-line differentiation of biotic and abiotic particles. The methods and devices are used to ensure quality and to monitor production as well as in analysis procedures for particular contamination's of gaseous media. The methods and devices are chiefly used in pharmacology, food technology, medicine, biotechnology and health care and in controlling maximum admissible concentration values. According to the inventive method, the gas sample to be measured is briefly heated at very high temperatures in a heating chamber (3). Dimensional distribution of particle contamination is determined before and after heating by means of diffuse light sensors (1, 2). Dimensional changes of biotic panicles caused by heating make it possible to determine their proportion in total particle load of the gas sample and their composition.
