Water-soluble organic carbon

Organic carbon (OC) and elemental carbon (EC) concentrations in smoke aerosol can be measured by using a semicontinuous thermal-optical OC/EC instruments [18]. Water-soluble organic carbon (WSOC) and water-soluble ions can be detected in smoke plumes with a PILS combined with a total organic carbon analyzer [30] and IC [19]. Besides smoke-specific tracers, the HR-ToF-AMS enables to study the concentrations of organic matter (OM), nitrate, ammonium, sulfate, and chloride in smoke particles [30]. Black carbon (BC) can be measured in real-time with several instruments, e.g., with aethalometer [19], multi-angle absorption photometer [29], and particle soot absorption photometer [25].

The wet chemical methods are summarized in Table IV. Basically this approach centers on the water-soluble extract obtained from Alter substrates, impactor plates, or other collection surfaces. The extraction process has to be done with some care to ensure that all of the water-soluble material is removed. Standard extraction methods now involve the use of ultrasonic devices to maximize extraction efficiency. Once the extract is obtained, it can be subjected to a number of the methods listed in Table IV, such that a detailed elemental breakdown by inorganic and (water-soluble) organic carbon is accomplished.
