Analysis of PFAS (VT-50 2D)
3 Mar 2023PFAS (per- and poly-fluoroalkyl substances) are not often decomposed in the environment and contain substances that are subject to the Stockholm Convention on Persistent Organic Pollutants (POPs). Their persistence in the environment and accumulation in living organisms are concerning. In this application note, HILICpak VT-50 2D, a polymer-based HILIC mode column, was used to analyze 9 kinds of PFAS and 3 kinds of haloacetic acids.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
