Elevating the temperature in the vaporizer and the sampling depth to 10 mm
The interferences become prominent when the depth from the sampling orifice is insufficient (<10 mm); however, higher depths reduce 18OH+ interference and increase 19F+ intensity. Can be used for gaseous FCs even if the molecules contain oxygen atoms.
Suitable for analysis of samples containing multiple FCs and quantification of unknown FCs with respect to their fluorine content. HPLC reduces a significant amount of interferences from metal ions.
The undetectable FCs in ESI-MS were detected in ICP-MS. Can be used to mine ESI-MS data. O2 could not eliminate carbon-based interferences. The use of O2 increased interferences from138Ba16O1H+
