- Opacity
    Opacity is the degree to which the transmission of light is reduced or the degree to which visibility of a background, as viewed through the diameter of a plume, is reduced.  A transmissometer (or opacity analyzer) measures the amount of light that is lost to scattering or absorption in the emission's effluent.  It is expressed in percentage usually, but sometimes in Ringelmann numbers.

- Chemiluminescence
    The method of detection where a chemical reaction generating light is used to measure the amount of Oxides of Nitrogen (NOx) found typically in a combustion process flue gas.

- NDIR (Non-Dispersive InfraRed) 
    By passing infrared energy through a cavity to a detector the measurement is based on the difference in response of the detector with the gas-of-interest present in the cavity versus its response with no gas of interest in the cavity.

- Flame Ionization
    Flame ionization is the method of detection where the total amount of carbon atoms (THC-total hydrocarbons) in a gas stream is determined by a measuring a minute current proportional to the amount of THC present in the combustion chamber.
