2B-Technologies - Black Carbon Photometer - Operation Manual

The Black Carbon Photometer (BCP) is a rugged, portable, highly accurate and economical instrument for measuring atmospheric black carbon particulates in polluted urban environments.  The BCP uses the simple and direct technique of long-path photometry to quantify—in real time—the total extinction and mass concentrations of particulates in the aerosol (gas + particle) phase.  This direct approach avoids the artifacts and other issues associated with current commercially available instruments, such as the most common current technique of aethalometry that uses filters to preconcentrate samples for analysis.
