Welcome to another Restek Tip. And in this discussion, we\u2019re going to focus on the importance of cleaning our gases when doing gas chromatography.<\/p>\n\n\n\n<p>So, let\u2019s talk about our carrier gas, for example. We\u2019re concerned about three principle contaminants with that \u2013 oxygen, because it can damage most GC capillary columns;&nbsp;hydrocarbons;&nbsp;and water. They can contribute background and other signal problems. And, even if we\u2019re purchasing high-purity carrier gas, and we should be, we\u2019re still going to want to filter because these contaminants can be introduced through leaks or other ways they can migrate into the system such as a bad tank of gas, too. Now, not all of our gasses fall under that same situation though.<\/p>\n\n\n\n<p>Let\u2019s talk about a fuel gas for our FID, for example.&nbsp;Our FID uses an air-hydrogen&nbsp;flame. We&nbsp;need the oxygen for our flame.&nbsp;But it is still important to filter out hydrocarbons and moisture. Those can contribute to baseline problems with getting a good, stable detector signal. So, again, different gas, different situation;&nbsp;but,&nbsp;still important to filter some critical contaminants from it. So, as you look at the gasses that are being introduced into your system, choose the right filters to remove the critical contaminants from each of those gasses to get the best performance for your application.<\/p>\n\n\n\n<p>Thanks very much for joining us for this Restek Tip.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Between fuel and carrier, we can flow a lot of gas through our GC.
