aosacsm

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.

Mass concentration of ammonium, ambient aerosol in air.
Mass concentration of total organics, ambient aerosol in air.
