Detection and concentration determination of 2,3,3,3-tetrafluoro-2-(1,1,2,2,3,3,3-heptafluoropropoxy) propanoic acid by LC/MS/MS

A method for detecting GenX in a sample comprising:

• injecting a sample into an LC/MS/MS system that is configured to detect GenX within the sample, wherein the LC/MS/MS includes ESI;
• subjecting the sample to ESI conditions that include a sheath gas heater setting of approximately 150° C. to approximately 275° C.;
• and
• detecting GenX within the sample.

A GenX detection system comprising:

• an LC/MS/MS system operable utilizing ESI and configured to:
• receive an injection of a sample containing GenX;
• subject the sample to ESI conditions that include a sheath gas flow of approximately 6 L/min to approximately 11 L/min;
• and
• detect GenX within the sample.

A method for facilitating the detection of GenX in a sample comprising:

• obtaining a sample containing GenX;
• receiving data representative of test results of an analysis detecting GenX within at least a portion of the sample, wherein the analysis comprised the following steps a) and b):
• a) injecting a volume of the sample into an LC/MS/MS system with ESI that is configured to detect GenX;
• and
• b) subjecting the injected volume of the sample to ESI conditions that include a sheath gas flow of approximately 6 L/min to approximately 11 L/min.
