Restek
About us
Established in 1985, at Restek we are dedicated to providing our clients and customers with the highest quality chromatography supplies and customer service available.
We offer a wide range of GC Columns, LC columns, GC/LC accessories and reference standards, as well as products for air sampling and sample preparation.
Products & services
Raptor Polar X LC Columns
Raptor Polar X columns let you easily analyse acidic, basic, and neutral polar compounds without time-consuming derivatization or complex ion pairing. The unique hybrid phase switches between HILIC and ion-exchange retention modes with simple mobile phase changes and short equilibration times. Ideal for a wide range of polar analytes, especially when coupled with mass spectrometry.
Rxi SVOC-ms GC Columns
Designed specifically for semivolatiles (SVOC) analysis, the Rxi-SVOCms column ensures consistent performance that will keep calibrations passing longer so more samples can be run before needing to recalibrate the instrument or replace the column. New polymer and deactivation chemistries produce highly inert columns with tightly controlled selectivity, resulting in exceptional performance for a wide range of analytes (acidic, basic, and neutral). Rxi-SVOCms columns are tuned specifically to improve peak shape for challenging SVOCs. For chemists in the environmental industry who are slowed down by variable column performance, frequent calibration failures, and poor column lifetimes, switching to rugged Rxi-SVOCms columns can ensure data requirements are met longer and downtime is minimised

Raptor Biphenyl LC Columns
The innovative Biphenyl is Restek's most popular LC stationary phase because it is particularly adept at separating compounds that are hard to resolve or that elute early on C18 and other phenyl chemistries. By bringing the speed of SPP to the Biphenyl family, the Raptor Biphenyl column provides clinical labs with an even faster option for a wide variety of clinical assays.
Low-pressure GC/MS
You can analyse multiresidue pesticides in just a third of the time using low-pressure GC-MS (LPGC-MS) instead of conventional methods. While LPGC-MS can be difficult to implement manually, Restek’s factory-coupled, low-pressure GC column kit makes setup simple and ensures consistent, leak-free performance.
