TY - CONF A1 - Simon, Fabian A1 - Wittwer, Philipp A1 - Meermann, Björn T1 - An optimized HR-CS-GFMAS method for PFAS analysis N2 - HR-CS-GFMAS turned out to be a sensitive, fast and highly selective tool for fluorine determination. The method is based on the in situ formation of diatomic gallium-mono fluoride (GaF) at a temperature of 1550°C. GaF can be detected at 211.248 nm providing limits of quantificationin the low μg/L range. However, several species specific effects where observed when analyzing PFASs.
