Bile Acids Interferences in PFAS Analysis

Bile acids structure and name

Can bile acids found in plasma, eggs, liver and other biological samples interfere with PFAS analysis? Yes! But there are ways to avoid these interferences and produce reliable data. Bile acids and their salts are either synthesized in the liver or formed from bacterial activity. They are the major constituents of bile and help digest […]

SGS AXYS Scientists Publish Timely Study on PFAS Storage Stability

While perfluorinated carboxylates and sulfonates (PFAA) such as PFOA and PFOS are known to be stable under all storage/environmental conditions, it is well known that many other PFAS, including PFAA precursors can transform in the environment from biological and chemical processes. But little was known about their stability in environmental samples sent to laboratory and […]
