acsm > Aerosol Chemical Speciation MonitorInstrument Type(s) > Baseline • Guest

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.

Purpose

Data are used to determine the chemical composition of the aerosol and help identify the source.
