The Magee Scientific Carbonaceous Aerosol Speciation System, model CASS, is a combined unit of a Total Carbon Analyzer, model TCA08 and an Aethalometer, model AE33 providing a revolutionary scientific instrument that measures the Total Carbon Content(“TC”), the Elemental Carbon content(EC), the Organic Carbon content(OC) and the Black Carbon content (BC) of suspended aerosol particles in near-Real Time.
The Magee Scientific Carbonaceous Aerosol Speciation System CASS provides a real-time data for BC, closely related to EC, and automatically combines them with TC data from TCA to provide a complete characterization of the carbonaceous component of the aerosol in near-real-time: TC, BC, (or ´EC´) and OC. The characterization of all carbonaceous aerosol components is perbed by including a simple mathematical relation: TC = BC (EC) + OC.
The Magee Scientific Carbonaceous Aerosol Speciation System CASS instrument discriminates a Black Carbon fossil fuel from a Black Carbon biomass burning (%BB) in real-time through a sophisticated built-in SW analysis based on a two-component Aethalometer model.
The BC (´EC´) optical analysis is perbed at 7 wavelengths from the near-infrared (950 nm) to the near-ultraviolet (370 nm) yielding optical absorption characteristics of collected aerosols on a teflon-coated glass fiber filter tape. Tape advances automatically when user selectable loading threshold is reached, typically once every few hours depending on aerosol concentration and air flow-rate.
The Magee Scientific Carbonaceous Aerosol Speciation System CASS is constructed in a rugged and compact design to fit AE33 and TCA08 into 19” rack type CASS housing package suitable for field-work, laboratory and routine Air Quality monitoring applications with limited space. CASS can operate for longer period of time (from weeks to months) without operator´s attention, only a roll of filter tape on AE33 and quartz fiber filter or denuder on TCA08 have to be replaced from time to tim
