The aerosol chemical speciation monitor is a thermal vaporization, electron impact, ionization mass spectrometer that measures bulk chemical composition of the rapidly evaporating component of sub-micron aerosol particles in real time. Standard measurements include mass concentrations of organics, sulfate, nitrate, ammonium, and chloride.
