Incorporating ultrashort-chain compounds into the comprehensive analysis of PFAS

Ultrashort-chain (USC) per- and polyfluoroalkyl substances (PFAS) are highly polar compounds with carbon chain lengths shorter than C4. Its widespread presence and elevated concentrations in aquatic environments are becoming a major concern, comparable to the well-known issues linked to long-chain PFAS contamination.

As such, it is crucial to analyze both USC and long-chain PFAS together in water samples to comprehensively assess and address the full spectrum of PFAS contamination.

Join Dr. Shun-Hsin Liang, Senior Principal Scientist of LC Solutions at Restek, as he explores the simultaneous analysis of C1 to C14 perfluoroalkyl carboxylic and sulfonic acids, along with other PFAS types, using two alternative chromatographic approaches, a hybrid HILIC/ion-exchange column and a polar-embedded alkyl phase column. He will also discuss how inert-coated columns can increase sensitivity.

Key learning objectives:

• Learn two viable solutions for the analysis of ultrashort-chain PFAS
• Understand how these solutions can be applied across a range of water matrices
• Discover how inert-coated columns can increase sensitivity

Who should attend?

Method development specialists, research chemists, and operation scientists interested in PFAS analysis.
