The California Analytical Instrument 700LX Series HFID Analyzer is designed to continuously measure the total concentration of hydrocarbons in various processes. The analyzer exhibits superior sensitivity and response time. The 700 series hydrocarbon analyzer uses the principle of Flame Ionization Detection (FID) to determine the total hydrocarbons in gas samples. The HFID analyzer has a heated oven (191 C) containing a burner and an optional heated pump. The burner flame is enhanced and maintained by the regulated airflows 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 biased using a precision power supply and the other electrode, known as the 'collector' is connected to a low impedance electronic amplifier. The two electrodes create an electrostatic field. When gas is introduced into 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.
CAI FID analyzers can measure THC or CH4 in ppm or percentage levels. They are ideal for applications such as:
- VOC reduction / scrubber efficiency
- Internal combustion engine test
- Continuous Emission Monitoring (CEM)
- Vehicle emissions
- Monitoring digestion process
- Detection of breakthroughs in coal beds
- Process analysis
