SSI-LCMS-102

■ Summary and Conclusions
The Shimadzu LCMS-8045 exceeds the performance
criteria specified by EPA Method 537.1 for all specified
compounds. Method detection limits ranging from 0.48 to
1.64 ppt were obtained with recoveries of at least 80% for
all compounds. The Shimadzu LCMS-8045 achieves rapid,
reliable and highly sensitive quantitation of PFAS in
drinking water by method 537.1. The LCMS-8045 can
easily be upgraded to a LCMS-8050 or a LCMS-8060 for
improved method detection limits. A 5 uL injection volume
was used in contrast to the 10 uL injection described in
EPA Method 537.1, making the method more robust and
reducing long-term cost of ownership.
