100 % polyethylene glycol columns, also known as WAX columns, are used for a wide variety of applications, such as industrial chemicals, flavours and fragrances. In comparison to polysiloxane stationary phases, the maximum operating temperature of a traditional WAX GC column is much lower, mainly up to 250/260 °C. Today’s demanding GC and GC/MS applications can have us pushing the boundaries of a column’s phase to decrease run times or limit potential carryover. But what happens when you go above the recommended temperature limit? We will discuss what the temperature limits mean, what can happen when they are exceeded for WAX type columns and which consumables can help increase the lifetime of these columns. We will also present a new WAX column that can safely achieve upper temperatures of 280/290 °C, what this will do for your run times and the applications you are now able to access.

What does it cover?

  • WAX type GC columns, Maximum Temperature Limits, how to protect your column from oxygen, and how to reach higher temperatures without sacrificing selectivity.

By viewing this on-demand webinar you will learn:

  • what the Maximum Operating Temperature means, what can happen when it is exceeded, and how to decrease your risk of damaging your WAX column.

Why should you view it?

  • To gain better understanding of how gas quality, thermal stability and column bleed can affect your chromatography.

This presentation is suitable for...

  • Laboratory technicians, researchers, and scientists wishing to learn more about GC columns and consumables that increase work efficiency.
