| Outline of Final Research Achievements |
Liquid chromatography (LC) with pre-column fluorescence/MS derivatization methods have been developed to determine the perfluorinated-alkyl compounds (PFCs), such as perfluorooctanoic acid (PFOA) and fluorotelomer alcohols (FTOHs). These methods are based on the derivatization with some pyrene and DMEQ reagents, the LC separation on PFC-modified reversed-phase column, and the sensitive detection by fluorimetry and/or the selective detection by MS/MS. Examined LC column can retain specifically PFCs by means of fluorophilic or “fluorous” interaction. Therefore, by using this technique, effective separation of the derivatized-PFCs from excess reagents and some matrix components could be achieved, and highly specific analysis was enabled by the fluorescence or MS detection. The proposed methods based on fluorous interaction will enable sufficiently sensitive and selective analysis of PFCs in many different types of real samples.
