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).

Whether you need to replace your existing bellows/diaphragm valves or want the extra sample security of using two valves in tandem, RAVEqc quick-connect air valves are a tool-free, easy-to-use option that will make air sampling and analysis much easier. No wrenches means there’s no risk of over-tightening or cross-threading damage and anyone can make the same quality connection. There’s never any question about whether the valve is open because you can tell at a glance. If the male and female valves are connected, the flow path is open. If they aren’t, it’s closed.

Designed with GC-MS users in mind, the GC Accelerator kit provides a simple way to speed up sample analysis. By reducing oven volume, these inserts allow faster ramp rates to be attained, which reduces oven cycle time and allows for increased sample throughput and more capacity to process rush samples. When faster ramp rates are used, existing methods can be accurately scaled down to smaller, high-efficiency, narrow-bore columns using Restek’s EZGC method translator. With a scaled-down column, a properly translated method, and a GC Accelerator kit, you can obtain the same chromatographic separation—often with greater sensitivity—in a fraction of the time without making a capital investment.
