Get More Than Just a Column

Zebron GC columns are engineered by expert Phenomenex GC scientists to better support our Gas Chromatography consumers. Our inventive philosophy and expertise in GC column manufacturing has resulted in 3 R&D 100 Awards, an honor that no other GC manufacturer has received.

Our Innovation, Your Success

In 1997, Phenomenex acquired GC manufacturing capabilities from Dr. Robert Wohleb, the “W” of J&W Scientific. We set out to pioneer the development of a new family of GC columns, and in 1999 the original Zebron columns came to life! The Zebron column family continues to evolve to help overcome obstacles you face every day our innovation comes from solving real world GC problems.

What’s in the Zebron PLUS?

Active sites on a GC column’s surface can result in analyte adsorption and degradation, which negatively affect peak shape and response. To recur pontential surface activity, Zebron PLUS phases ZB-1PLUS, ZB-5PLUS, ZB-5MSPLUS, and ZB-624PLUS) are designed with a rigorous fused silica deactivation process that improve inertness and peak shapes for troublesome compounds. Zebron ZB-WAXPLUS is specially designed for 100% aqueous stability, enhanced resolution, and better reproducibility.

A. Low bleed phase chemistry
B. Clean, highly inert fused silica surface due to very few active sites
C. Temperature resistant and flexible coating
