I'm working with a custom re-built trace analytical RGD2 for trace analysis of Hydrogen and CO at atmospheric background level (500 ppb for H2 and 250 ppb for CO more or less). I use a Unibeads 1S precolumn and Mol Sieve 5A main column with He carrier gas, 20 ml/min. My question is: H2 peak is poorly resolved from the following peak, should be Oxygen eveni f I don't have any information on this. Do somebody have experience with a similar configuration? And in case this second peak is oxygen, why is detected by RGD?
thank you
