  • Methane (CH4) Analyzers Nova Gas

    Methane is a gas of interest in many analytical applications. Infrared (IR) detectors can be used to measure CH4 because it is an excellent absorber of infrared energy. Methane in industry is frequently measured in percent (%) ranges, but parts per million (ppm) measurement is also possible with IR detectors. Nova equipment measures CH4 using an IR detector that also sees other hydrocarbons and reports them as methane.
