Application scope:

*Atmospheric aerosol black carbon monitoring;

*Monitoring of atmospheric radiation transmission;

*Monitoring of aerosol particle size distribution;

*Monitoring of aromatic compounds with UV absorption;

*Monitoring of combustion emissions of carbon containing substances;

*Monitoring of combustion emissions from internal combustion engines;

*Other applications of black carbon analyzer:

The black carbon analyzer calculates the concentration of black carbon aerosols based on the attenuation of transmitted light caused by black carbon aerosols on the sampling film, and therefore can also calculate the optical absorption coefficient of aerosols;

Using the thermal optical carbon analysis method to measure the elemental carbon (EC) aerosols on the sampling film, and comparing the results with the optical method for measuring black carbon aerosols (BC), establish aCompare different measurement techniques.

AE51 is a handheld micro black carbon analyzer that uses the Aethalometer optical absorption method to sample and analyze the mass concentration of black carbon aerosols in the air in real time.
