The Next Generation of GC Inertness
Zebron ZB-624PLUS is the optimal choice for the analysis of volatile compounds for Environmental, Pharmaceutical, Food, Cannabis, and Specialty Chemicals. The superior “Plus” deactivation process enhances peak shape, improves signal-to-noise levels and increases sensitivity for qualitative and quantitative analysis of active compounds. Upgrade your existing 624 phase to Zebron ZB-624PLUS GC columns and get all the analytical benefits of proven inertness.
- Enhanced peak shape with superior deactivation
- Increased sensitivity for high boiling solvents
- Extremely low bleed for GC-MS
- High temperature stability (300/320 ºC)
What makes the PLUS in ZB-624PLUS?
Low Bleed
- Engineered Self Cross-linking™ (ESC™) provides high thermal stability with maximum column temperatures up to 300/320 °C.
Enhanced Inertness
- Proprietary superior deactivation gives great peak shape for troublesome compounds.
High Selectivity
- A G43 phase that’s highly selective for polar, non-polar, low and high boiling solvents.
Column-to-Column Reproducibility
- Excellent column-to-column reproducibility well suited for validated methods.
Temperature Limits
- Push the temperature limits of traditional 624 and elute/ bake high boiling analytes at 300/320 °C.
MS Certified
- Low bleed characteristics makes it the right choice for GC-MS.

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.
