Natural gas or digester gas? Ethane analysis and its application in gas leak detection

Sometimes we find gas leaks that we can`t explain. The measurement technology shows that the gas found is flammable, but there is no obvious damage site. Repeated measurements continue to show gas emissions. The cause could not only be a defective natural gas pipeline, but also digester or swamp gases (e.g., biogas from fermenters, landfill gas, mine gas, cemetery gas or even fuel).
