The Sunset Laboratory Carbon Aerosol Analysis Lab Instrument is widely used for thermal-optical analysis (TOA) of ambient particulate matter samples to measure total carbon (TC), organic carbon . The EC/OC analyzer (Sunset Laboratory Inc., Portland, OR, USA) is an instrument designed for the measurement of EC, OC, and four OC volatility fractions (OC 1 -OC 4 ) in carbonaceous aerosols .three filters per batch, whichever is larger, and analyze for lab blank OC and EC. The blank filter must have OC < 11 µg C/filter and EC < 2.0 µg C/filter. If any lab blank filter has a carbon loading over the above limits, analyze three more filters. If the OC and/or EC are still over these limits, all filters from the same batch are discarded.Interestingly, the isotopic composition of the individual carbon fractions show a large isotopic difference between OC and EC (D 13 C OC2EC ¼ d 13 C OC 2d 13 C EC ) in the forest sample, but a .
Sunset Carbon Aerosol Analysis Field Instrument was developed, which measures OC 20 and EC in situ and in near-real time, based on the same analysis principle as in the Sunset laboratory instrument (Bae et al., 2004). However, the field instrument will not be further described in this review as it performs on-line measurements while the labcarbon. Elemental carbon is naturally present in many of these samples from some combustion source such as a diesel exhaust. This black material is a very strong absorber of light, and almost always the only absorber in the red light region. In addition to this elemental carbon in the sample, elemental carbon can be formed from some charring ofThe Semi-Continuous OCEC instrument is a field deployable alternative to integrated filter collection with subsequent laboratory analysis.
