Applications: In mixture with argon, methane is used in Geiger counter and for the detector in X Ray Fluorescence (XRF) as quentching gas. In mixture with other hydrocarbons, methane is used as reference point in calorimetric measurements for the measurement of PCI of hydrocarbons or coal. Methane is used in calibration gas mixtures for petrochemical industry; environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers.
