Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX and many other chemicals. They have been manufactured and used in a variety of industries around the globe since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both are very persistent in the environment and in the human body - meaning they don't break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects. 

The United States Environmental Protection Agency (USEPA) has issued drinking water health advisories for two PFASs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) at 70 ng/L. As the research surrounding these problematic, lifelong chemicals becomes more expansive, the need for sensitive and specific extraction methods becomes more vital for accurate detection and quantitation.

UCT is the 35+ years premier environmental analysis provider, featuring an extensive range of turnkey solutions, ranging from sample prep columns, to QuEChERS configurations, to processing stations all the way to analytical columns.

What's included?

Sample Prep/Consumable Solutions
Learn all about UCT’s SPE cartridges that feature enhanced cleanliness for minimal background in addition to unrivaled exchange capacities.

Sample Processing
UCT’s complete PFAS glass block processing station and accessories provide all facets needed for an efficient extraction. All components are hand-selected to minimize potential for any secondary background contamination.

PFAS Food Safety Testing Solutions
In 2019, the FDA expanded the methods used in earlier testing and made available the first single-lab validated scientific method for testing 16 different types of PFAS in a highly diverse sample of foods (fruits and vegetables, bread, milk, cheese, other dairy, meat) utilizing a UCT QuEChERS approach.

Separations/Analytical Columns
UCT provides robust and cost-effective Selectra® C18 column solutions that maximize resolution and sensitivity for PFAS analysis, together with corresponding delay columns to capture any unwanted background contamination in mobile phase, solvent lines, and online degassers.
