Gas Chromatography

Pushing upper temperature limits for WAX columns...

Want to know what extending the upper temperatures limits of your WAX columns will do for your run times and applications? Watch this presentation to find out...

WAX columns (100 % polyethylene glycol columns), are used for a wide variety of applications, such as industrial chemicals, flavours and fragrances. These columns are used at lower temperatures than polysiloxane columns, but many newer applications require higher temperatures - so what happens when you push these columns beyond their recommended temperature limits?

In this presentation, Vanessa Abercrombie, Gas Chromatography Applications Chemist, Agilent Technologies, USA, will present a new WAX column that can safely achieve upper temperatures of 280/290°C, and provides an explanation of what this will do for your run times. Vanessa will also highlight the applications that you are now able to access.

Furthermore, 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. You will also gain better understanding of how gas quality, thermal stability and column bleed can affect your chromatography.
