Abstract
An apparatus and method to capture aerosols and vapors on substrates from a large variety of sources and matrices for analysis using paper spray mass spectrometry (PS-MS) is disclosed. A holder for a PS cartridge has better direct sampling efficiency, direct capture on substrate, and lower limits of detection thereby improving the collection and analysis of aerosols and vapors. An apparatus and method for aerosol and vapor collection, from both anthropogenic and environmental sources, for example, that is compact and compatible with hand held devices and unmanned vehicles is also disclosed.
