|Use:||Analyzing halogenated SVOCs, PAHs, pesticides and herbicides, and PCBs.|
Room-temperature phosphorimetry is based on detecting the phosphorescence emitted from organic compounds absorbed on solid substrates at ambient temperatures (conventional phosphorimetry requires cryogenic (low temperature) equipment). Instrument design is similar to fluorescence techniques (see 6.2.12 and 6.2.13).
4. Halogenated SVOCs
