A CHROMacademy Essential Guide Webcast: Gas Quality for GC
Thursday 26th February 2015,
8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST
The quality of carrier gas used in a GC system is of the utmost importance. Gases which contain moisture, oxygen, or contaminants can have a serious detrimental effect on the GC system, GC column, and ultimately chromatographic results. The use of the correct gases for detectors is a must, with the cleanliness of the gas being an important factor. This webcast will discuss all of the important considerations on selecting the correct gas with the correct cleanliness for your GC system and detector. Common problems will also be highlighted in order for GC users to spot them quickly when they occur.
Presented by Tony Taylor (Technical Director, Crawford Scientific).
