This Application Note describes the combination of the Carbonaceous Aerosol Speciation System (CASS) and an Aerosol Chemical Speciation Monitor (ACSM).

The ACSM is used for real-time monitoring of non-refractory aerosol particle mass and chemical composition.  It reports particulate ammonium, nitrate, sulfate, chloride, and other organic species as “organic matter” (OM).  The ACSM is one component of the standard equipment used at ACTRIS monitoring stations to determine organic matter (OM) within the PM2.5 and PM1 fractions. (https://www.actris.eu/). The Magee Scientific Carbonaceous Aerosol Speciation System (CASS) combines the TCA08 Total Carbon Analyzer and the AE33 Aethalometer. This creates a revolutionary instrument for the determination of the Total Carbon (TC), the Elemental Carbon (EC), the Black Carbon (BC), and the Organic Carbon (OC) content of suspended aerosol particles in real-time.
