New study reveals which GC columns can withstand temperatures of 400 °C for extended periods of time

Traditional GC columns are made from fused silica with a polyimide outer coating, which is ideal for most applications. However, temperatures above 360 °C degrade this coating and reduce the physical strength of the column—making it susceptible to breakage.

Agilent J&W high-temperature GC columns feature a high-temperature polyimide that can operate in temperatures of up to 400 °C. They combine robustness with advanced surface deactivation for improved column lifetime and peak shape. In addition, they feature advanced stationary phase bonding for low bleed performance at high temperatures.

What about applications operating higher than 400 °C?

For applications above 400 °C, metal GC columns offer better durability and ruggedness than fused silica tubing. Agilent J&W UltiMetal and DB-ProSteel deactivated stainless steel GC columns last long even under extreme conditions.

We wanted to see which columns withstood high temperatures best.
So, we put them to the test.

In our study, we compared Agilent high-temperature GC columns with columns from different suppliers.
Here’s what we found:

At-a-glance guide to choosing GC supplies

The right GC supplies deliver cost-saving advantages—like less rework, maintenance, and downtime. Our easy-reference chart will help you select the best GC supplies for standard and high-temperature applications.

All columns do not have the same thermal stability and efficiency

The Agilent J&W DB-5ht GC column has an extended temperature range of up to 400 °C, so the fused silica tubing and phase can operate safely for an extended time.

Metal columns can take the heat better than fused silica columns

Agilent UltiMetal and DB-ProSteel deactivated stainless steel columns have an even internal surface, and provide a safer option for applications operating above 400 °C. They are available with identical phases as their fused silica counterparts.
