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

Meet your Zebron ZB-624PLUS GC Column
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 |
| Enhance 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. |
Low Bleed = Better Signal-to-Noise Ratio = Lower Detection Limits
The low bleed character of ZB-624PLUS™ columns is the result of advances in cross-linking manufacturing processes that we established for these columns.
With ZB-624PLUS™, your GC column undergoes proprietary cross-linking process to get extensive Engineered Self Cross-linkage (ESC™).

Improved Peak Shape of Volatile Amines
Volatile amines are challenging analytes for GC analysis. They can adsorb to even the smallest imperfections in fused silica. ZB-624PLUS™ undergoes a superior deactivation process which minimizes active compound adsorption leading to gains in Peak response and shape

“YES!”
The number of plates is better for later eluting (higher boiling) solvents. We can use this column directly for routine analysis, with the bonus that higher temperatures can be used! – Dr. Marek Mahut, Novartis, SwitzerlandThe opinions stated herein are solely those of the speaker and not necessarily those of any company or organization.
