Detection and Differentiation of Liquid and Solid Particles in Ambient Air

Abstract

Aerosols contain liquid and/or solid particles, which can pose a significant risk to humans. In order to detect these potential hazards at an early stage, this paper shows the possibility of measuring aerosols with an adapted particle sensor system (ProxiCube®) and displaying the liquid and solid components separately. To demonstrate the reproducibility of the measurements, samples are monitored simultaneously with two ProxiCubes and a well‐established reference system.
