The California Analytical Instruments Model 600 FID Analyzers are designed to continuously measure the total concentration of hydrocarbons within a gaseous sample. The analyzers exhibit superior sensitivity and response time. The gaseous sample can be exhaust gases from an internal combustion engine, a combustion process or VOC abatement systems.

Method of Operation

The California Analytical Instruments’ Model 600 FID Analyzer utilizes the principle of Flame Ionization Detection (FID) to determine the total hydrocarbons within a gaseous sample. The FID analyzer has a heated burner (550C) which contains a burner and an optional pump. The small flame of the burner is elevated and sustained by the regulated flows of air and either pure hydrogen or a 40/60 mixture of hydrogen and helium, or nitrogen. The split ring detector contains 2 electrodes. One electrode is negatively polarized using a precision power supply and the other electrode, known as the “collector” is connected to a high impedance, low noise electronic amplifier. The two electrodes establish an electrostatic field. When a gaseous sample is introduced to the burner, it is ionized in the flame and the electrostatic field causes the charged particles (ions) to migrate to their respective electrodes. The migration creates a small current between the electrodes. This current is measured by the precision electrometer amplifier and is directly proportional to the hydrocarbon concentration of the sample.
