Magee Scientific SootScan Model OT21 Optical Transmissometer Aethalometer
Made in Slovenia
Manufacturer Description
The SootScan™ Model OT21 Optical Transmissometer benchtop analyzer is a simple and robust instrument that measures the Black Carbon content of an aerosol sample collected on a filter, either from ambient air or from source emissions.
The SootScan™ Model OT21 Optical Transmissometer can analyze aerosol samples quickly and easily in the field or the laboratory to determine optical attenuation and BC / BrC mass results. The analysis is performed at two wavelengths (880 nm, definitive for “Black” Carbon; and 370 nm, where enhanced optical absorption may indicate the presence of “Brown” Carbon aerosol derived from biomass combustion.)
The analysis is non-contact, non-contaminating, and non-destructive. It may therefore be performed before other laboratory techniques are applied to the sample. The analysis method requires no support gases or consumables. A neutral density photometric standard kit is available for verifying instrument calibration and validating the instrument response.
