It is frequently used as a detector in gas chromatography. In gc, liquid samples are vaporized, then carried by an inert gas through a long, thin column. In particular, accumulations of hydrogen. High pressure gas frequently check gas flow lines for leaks. Principle fid consists of a hydrogen/air flame and a collector plate. This universal detector, which is also characterized due to its higher acquisition speed, comparable to that of fid 41, this detector has demonstrated a good performance in the analysis of diesel.
Each detector requires gas, called the detector gas, based on its principle of detection. Many gc problems can be prevented if the column is properly installed and gc is maintained routinely. Principle of fid operation setting the detector setting the detector gas flows thermal conductivity detector (tcd) principle of tcd operation do not touch the back of the gc near the exhaust. Flame ionization detectors work on the principle of ions liberated in the combustion of the sample species.
