Sulfr hexafluoride analysis with TCD - Baseline failure after O2 peak

When a pure standard (gaz sf6 in N2) is used, this problem disappears due to low O2 contamination. However, when I inject a sample of gaz sf6 in air, the baseline fails to return level after the (negative) O2 peak. As a result it swallows the insulating gas peak and gives an erroneous area value.Get price
