Background PFAS (Perfluoronated Alkyl Substances) from an LC instrument and mobile phase can interfere with the detection of PFAS in samples. The introduction of a delay column, which is plumbed before the autosampler in the LC system, will delay background PFAS to improve accuracy of PFAS measurement by LC-MS.​

• Silica-based fully porous particle delay column
• Universal, can be used in a workflow setup with any analytical column format/dimensions

Allows for the analysis of PFAS from the sample, without interfering PFAS compromising the analysis (present and introduced by the instrumentation). Moreover, the data output/chromatogram benefits with the respective PFAS sample peaks separated/delayed from the background PFAS peaks.
