Overcome Traditional Obstacles

Challenge # 1: Short Fused Silica Column Lifetimes

Unlike Zebron™ Inferno™ GC columns, traditional fused silica columns are not equipped to handle prolonged exposure to
temperatures above 360 °C. At high temperatures, fused silica GC columns:

• Become inflexible and brittle
• Break easily and cause costly replacement
• Require more system downtime for maintenance
• Can’t separate high molecular weight compounds

Challenge # 2: Cumbersome Metal Column Tubing

Though metal columns have higher temperature limits than capillary columns, they are more difficult to use.

Most metal columns:

• Are inflexible and hard to use
• Require special tubing cutters for installation
• Are prone to leaks from expansion and contraction
• Have active surfaces, giving poor peak shapes for acids and bases
• Are incompatible with MS detectors

How it works

Zebron™ Inferno™ columns offer enhanced performance where other columns fail. The two critical factors that allow for this are:

• Advanced ESC™ Bonding Technology

At high temperature ranges, the stability of standard GC columns deteriorates, resulting in increased bleed. Zebron’s Engineered Self Cross-linking™ (ESC) bonding technology reinforces the stationary phase for enhanced column durability and extremely low bleed levels at high temperatures. The result: Inferno columns with the flexibility to perform for high temp oven ramps and bakeouts.

• High Temperature Polyimide Coating

Standard polyimide resin pyrolyzes at temperatures above 360 °C, making the tubing unstable. Zebron Inferno columns use a temperature resistant polyimide resin that shows minimal thermal degradation, even at temperatures up to 430 °C*. This means longer column lifetime at elevated temperatures.

Features of Zebron Inferno GC Columns

Extremely Low Bleed for Rugged Performance

• Longer column lifetime
• Better reproducibility
• Maximum sensitivity
• More accurate quantitation

Increased Column Lifetime with Enhanced Durability

• Less instrument downtime
• More productivity
• Lower laboratory costs

Standard GC Columns Cannot Withstand High Temperature

After prolonged exposure to temperatures above 360 °C, most traditional GC columns become brittle and inflexible, often spontaneously breaking in the middle of a run. Work is stopped in order to change out the column and perform system maintenance. Unlike these fragile columns, ZebronTM InfernoTM columns have a thermally resistant polyimide coating for longer column lifetime at temperatures up to 430 °C. As a result, you get less instrument downtime, and higher productivity.

Greater Performance for High Boiling Compounds

• Better peak shape
• Improved separation
• More analytes detected

Zebron™ Inferno™ columns have the inertness and temperature stability needed to separate high molecular weight compounds. These high boilers require a thermally rugged column with low bleed levels. Inferno columns provide optimal separation of these analytes.
