Oxygen content

The hydrocracking unit system was shut down and nitrogen was used for purging; during the analysis of the high-pressure gas, the oxygen content kept increasing. Where is this oxygen coming from?
Were the sample bags new where they were obtained? Has the pressure remained positive? Is there any air leakage in the nitrogen?
First, you need to check what the levels of nitrogen and oxygen are in yours Whether it exceeds the standards, then there is the issue of sampling – taking samples multiple times. Finally, there is the matter of laboratory analysis, namely the operator’s skills and the accuracy of the equipment. r=Red]
It must have been brought in by nitrogen, or else the sample quality was poor.
