Here’s the Proof: PFAS Delay Columns Get Contaminants Out of the Way
You may not notice PFAS interferences if you are running highly contaminated samples because the background level is low in comparison. But if you are analyzing trace-level PFAS you could definitely be affected. Here’s proof that using a PFAS delay column gets system contaminants out of your way.
Environmental chemists and biologists have determined that PFASs may have harmful toxicological effects and pose a significant risk to the public. The USEPA published Method 537 for the determination of selected polyfluorinated alkyl acids in drinking water (14 compounds). Since the method’s publication, researchers have identified an additional 10 compounds of concern.
AccuStandard has responded to this growing concern by introducing new products such as PFC-24 which contains 24 of the fluorinated compounds of greatest concern.

Versatile radiello passive diffusive air samplers, feature a unique 3D radial design that provides several performance advancements compared to standard 2D flat axial air samplers. These samplers are a reliable, cost-effective alternative that offers both high sensitivity for low-level detection in short sampling periods (down to 15 min), as well as higher capacity so accurate results can be obtained over longer (30 day) sampling times.
The Polyarc has been described by a user in the chemical industry as, "another tool to help us solve the difficult questions asked of us every day." Polyarc users have routinely shared that the system has allowed them to save thousands of dollars, and the time savings associated with the reduction in calibration procedures has been invaluable.
We recognise that there is some confusion in the industry regarding the categorization and naming of chromatography vials; what follows are explanations for two of the most common questions we get asked:
