MS Certified “1” Phase
- Very low bleed (MS Certified) phase especially suited to high sensitivity GC-MS
- Extremely inert for active compounds such as drugs, pesticides, or acids and bases
- Improved signal-to-noise ratio for better sensitivity and mass spectral integrity
- Equivalent selectivity to 100 % dimethylpolysiloxane phases
We tested the ZB-1PLUS column bleed profile against other “MS” columns on the market – ZB-1PLUS shows the lowest bleed, even at temperatures up to 360 °C.

Phenomenex Zebron PLUS GC Columns
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 reduce potential surface activity, Zebron PLUS phases (ZB-1plus, ZB-5plus, ZB-5MSplus, and ZB-624plus) are designed with a rigorous fused silica deactivation process that improves inertness and peak shapes for troublesome compounds
- Zebron ZB-WAXPLUS is specially designed for 100% aqueous stability, enhanced resolution and better reproducibility.
