CAI FID analyzers rely on the Flame Ionization Detection principle to measure the total concentration of hydrocarbons in a gas sample. The gas sample becomes ionized in the flame and the electrostatic field causes the charged particles to migrate, creating a small current that is measured by the amplifier. The current is directly proportional to the amount of hydrocarbon in the sample. The 700 MHFID model measures Total Hydrocarbon and provides a means of differentiating between Methane and non-Methane hydrocarbons.
CAI FID analyzers can measure THC or CH4 in ppm or percent levels. They are ideal for applications such as:
