Description

Per- and polyfluorinated alkyl substances (PFAS) are a group of widely used industrial compounds that do not degrade and are ubiquitous in the environment and human samples from around the world. Because of their inertness, PFAS are used in tubing and other liquid-wetting parts of an HPLC system, where they can leach into the mobile phase and interfere with sample analysis. This contamination is particularly problematic in trace-level analyses, such as the ppt-level concentrations recommended for drinking water. Since many labs analyze single-digit ppt concentrations and aim for sub-ppt detection, PFAS contamination from HPLC components can prevent accurate identification and quantification of PFAS in samples. To eliminate this problem, Restek's new PFAS Delay Column captures system-borne PFAS and "delays" them so they cannot interfere with sample analysis. This delay column is a universal solution that can be used with any type of HPLC or UHPLC system up to 1034 bar (15,000 psi) and with any analytical column (fully porous or core-shell).

Particles: 5 µm, spherical, fully porous
pH range: 2.5 to 8
Maximum temperature: 80 °C
Maximum pressure: 1034 bar/15,000 psi

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
