Optical Carbon Analyzer

The additional optical information can be used to estimate multiwavelength light absorption of the sampled particles, quantify the concentration of brown carbon (BrC) in each sample, and further complement the use of carbon fractions in source apportionment studies. Model 2015 software includes temperature programs for commonly-used protocols such as IMPROVE_A, EUSAAR, and NIOSH, and it can be programmed to emulate any other protocol. The simultaneous measurement of both R and T at all wavelengths throughout each analysis allows for reproducing any other thermal/optical method and holds potential for better characterizing additional properties of the carbonaceous aerosol.
