Investigating the Influence of Selectivity in Bottom-Up Proteomics

Ultrapure water from a Milli-Q® water purification system was tested for PFAS according to the draft EPA 1633 method. None of the 40 PFAS compounds tested were detected in the ultrapure water produced by a Milli-Q® IQ 7000 system fitted with a LC-Pak® polisher at the point-of-dispense, making it suitable for the most sensitive PFAS analyses by LC- MS/MS.

This note demonstrates efficient PFAS extraction from contaminated surface water using automated mixed-mode µSPEed® cartridges and Tecan's Resolvex® Prep.

Crucial phosphorylated compounds can be analyzed by a polymeric iHILIC-(P) Classic HILIC column and MS. The method is applicable for targeted and non-targeted metabolomics.
