Abstract
Method for determining whether a gas sample originates from biological processes or from a gas installation being tested and containing a utility gas is characterized in that an increased concentration of hydrogen in the sample as compared to that present in the utility gas is used as evidence that the sample originates from biological decay processes and not from the gas installation under test.
