GC Columns

For over 30 years, Restek has designed and manufactured gas chromatography (GC) columns. From fused silica to metal MXT, from PLOT to packed, we offer a wide variety of both general-purpose and application-specific GC columns to analysts around the world. Our research team develops proprietary stationary phases and optimized GC column chemistries to span the full polarity range, making it easy to select a perfectly matched GC column that helps you run faster and produce outstanding results. Our Innovations lab generates applications for environmental, food safety, petrochemical, chemical, forensic, bioanalytical, and other industries—you’ll find the chromatograms here on the Restek website for your convenience—and the Restek Quality Control department measures against strict specifications to ensure that our GC columns exceed your expectations, as well as your customers’.

As an independent, employee-owned company, Restek is free to supply GC columns for every instrument, regardless of who made it. And our gas chromatography experts have extensive experience to provide you with the information you need about Restek GC columns, applications, troubleshooting, method development, and more. Best of all, each GC column that leaves our facility comes with an unbeatable guarantee: Restek Pure Satisfaction.

HPLC & UHPLC Columns

Since 1996, Restek has developed and manufactured liquid chromatography (LC) columns that are trusted by labs worldwide for easy, fast, and accurate results. We offer LC columns for the latest UHPLC systems as well as for your tried-and-true HPLCs, and because Restek is an employee-owned company, we are able to support every instrument platform with the same top-quality products, cutting-edge applications, and Plus 1 customer service.

When it comes to LC peak separations and, most important, peak resolution, selectivity is the most influential factor to consider—and it is what led Restek to develop Ultra Selective Liquid Chromatography (USLC) technology. USLC column sets offer the widest range of selectivity in the industry using just a handful of phases to simplify LC column selection for fast, effective method development.

In addition to bulk packings, guards, and hardware, Restek features the following LC column formats:
Raptor LC Columns: SPP, or “core-shell,” LC columns designed specifically to accelerate your analyses while maintaining reproducibility and ruggedness.
Force LC Columns: Premium, long-lasting, and reproducible LC columns for HPLC and UHPLC; fully scalable from 1.8 μm to 3 μm to 5 μm.
Roc LC Columns: Solid and dependable LC columns made for exceptional value and traditional HPLC use, particularly with USP methods.
Ultra LC Columns: High-purity, type-B silica that minimizes activity and creates high-density bonding for reliable HPLC use.
Pinnacle DB LC Columns: Restek-manufactured, base-deactivated silica support that is optimized for UHPLC column stability.
Viva LC Columns: Rugged, spherical particles with a wide 300 Å pore size and narrow distribution that are designed for large-molecule separations.
