High temperature Gas Chromatography applications using fused silica columns can be problematic for applications that run above 360 °C. Even if a phase is stable enough to maintain extended periods of time above 360 °C, the polyimide coating on fused silica will eventually burn off, causing the column to become brittle.

We will examine what effect temperatures above
360 °C will have on the integrity of the column phase and brittleness of the column over extended periods of time. We will discover strategies for more efficient and successful high temperature applications, such as utilizing metal columns, and how long they are able to operate at temperatures up to 450 °C and still maintain their integrity. We will also discuss how selection of the right consumables and maintaining a leak free system is especially important in high temperature GC applications, and how to pick the right ones to have a successful and robust GC analysis.

This presentation covers:

• high temperature GC columns
• maximum temperature limits
• how to protect your column from oxygen
• how to reach higher temperatures without sacrificing selectivity
• when to switch to metal columns
• which consumables are needed for high temperature applications.

By viewing this presentation you will learn:

• what the maximum operating temperature means
• what can happen to the phase and fused silica when it is exceeded
• how to successfully perform high temperature applications
• how to elute up to C₁₁₄
  
  

Why should you view it?

To gain better understanding of what high temperature gas chromatography means, when to use high temperature fused silica and when to switch to deactivated stainless steel GC columns, and
how gas quality and thermal stability can affect your chromatography at high temperatures.

Who should view it?

Laboratory technicians, researchers, and scientists wishing to learn more about high temperature GC best practices, consumables, and increase column lifetime for high temperature applications.
