With many labs analyzing PFAS at single-digit ppt levels or below, PFAS contamination from HPLC components can prevent accurate measurement of PFAS in samples. To eliminate this issue, Restek’s new PFAS delay column traps and “delays” system-related PFAS, preventing them from interfering with sample analysis. This delay column is a universal solution that can be used with any type of HPLC or UHPLC system up to 15,000 psi (1034 bar) and with any analytical column (fully porous or superficially porous).

These certified reference materials (CRMs) will help you meet the specific cannabis analysis needs of California set forth by the Bureau of Cannabis Control for regulated category I and II residual pesticide reporting—and of other states with similar regulations/programs. Ideal for creating multipoint calibration curves for GC- and LC-MS/MS, these six mixes eliminate the need for in-house standards prep. And, as with all CRMs manufactured and QC tested in our ISO-accredited labs, they will satisfy your ISO requirements.

Low-level detection of carbon monoxide (CO) and carbon dioxide (CO₂) is critical for many applications. Restek’s methanizer (CH₄izer) allows ppb-level determination of CO and CO₂ using a cost-effective FID instead of more expensive instrumentation. Up until now, the methanizer was only available for Agilent GCs, but Restek has just released a version of the methanizer for Thermo TRACE 1300/1310 GCs that features the same benefits to your lab as the original model.
