Measurement of TOC in Perfluorochemical (PFOS) Solution

PFOS is an extremely stable compound with strong carbon - fluorine bonds, and reports of its accumulation in wildlife and the environment have attracted international attention and concern, leading to the designation of PFOS as a persistent organic pollutant (POP).The persistent nature of PFOS prevents oxidative decomposition using wet chemical oxidation TOC analyzers; however, the Shimadzu high-temperature catalytic combustion TOC analyzer quantitatively recovers PFOS with high sensitivity and accuracy. Here, we demonstrate measurement of PFOS using the TOC-LCPH high-temperature catalytic combustion and the TOC-VWS wet chemical oxidation total organic carbon analyzers.
