Natural gas testing and analysis expertise.

Intertek laboratories provide natural gas quality and component analysis. Natural gas testing includes the analysis of conventional and shale gas, LNG, and other hydrocarbon condensates and components. Gases analyzed include hydrocarbons (C1 to C6+) such as methane, ethane, propane, iso-butane, n-butane, iso-pentane, n-pentane, and hexane, plus heavier molecules.

Natural gas labs test to trace detection levels for impurities. Natural gas trace impurities include hydrogen, nitrogen, carbon monoxide, carbon dioxide, oxygen, mercury, sulfur, water, and other components.
