PhD researcher Stephen (RenXi) Ye has developed the first GC-MS method capable of separating and quantifying C2-C14 perfluorinated carboxylic acids in environmental samples. The novel derivatization was designed to yield excellent selectivity with common GC stationary phases, plus we got explore H2 as a carrier gas! We applied this to tap, rain, and ocean water; as well as atmospheric sample extracts! Read more in the full manuscript, published this week in Analytical Chemistry:
