Abstract

An adjustable air sampler device and method for collecting airborne viable and non-viable aerosols and psychrometric data for room or remote air samples wherein the sample volume is electronically controlled. Aerosols in the air are caused to impact the surface of the growth/inhibitor media 20 or a polymeric lens 27 cartridge thereby depositing viable and non-viable aerosols on the media. The growth/inhibitor media may be a solid, liquid, gel, or mixture thereof. The polymeric lens may be a semi-permeable membrane device. Concentrations and identity of specific aerosols are determined. A chip-based sensor measures psychrometric properties of the air sample.
