    - 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.

    - Paramagnetic
      This detection method is based on the effect of magnetic lines of flux on oxygen molecules. The oxygen molecules tend to pool around the high intensity flux lines.

    - NDIR (Non-Dispersive InfraRed)
     
      This method of detection is based on the Luft detector; by passing infrared energy through two cells (reference & measuring) to a detector (the Luft detector) the difference in IR energy is determined; the higher the difference, the higher the concentration of the gas-of-interest. The detector is non-linear.

    - Flame Ionization
      Flame ionization is the method of detection where the total amount of carbon atoms (THC stands for 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. A hydrogen flame (from either pure H2 or a 40/60 mix of H2/He) liberates the carbon ions; the ions create a minute current flow to a collector plate; the current is measured and converted to (usually) a ppm concentration value.
