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 |
| abstract |
A method and system for injecting an unconcentrated sample into a receiving LC/MS/MS system that is configured to determine a concentration of GenX within the unconcentrated sample, wherein the LC/MS/MS includes ESI. The unconcentrated sample is subjected to the following ESI conditions: i) a probe gas temperature of approximately 120° C. to approximately 160° C.; ii) a sheath gas heater setting of approximately 150° C. to approximately 275° C.; and iii) a sheath gas flow of approximately 6 L/min to approximately 11 L/min. The concentration of GenX is determined within the unconcentrated sample, wherein the concentration of GenX within the unconcentrated sample has a minimum reporting level of approximately 0.010 μg/L. |
