Flame Ionization Detector for Gas Chromatography

Gas Chromatography as a Method for Estimating Concentrations of Volatile Anaesthetics in Blood

“…process in diagrammatic form, where the more volatile components are emerging before the less volatile. On emergence from the column the separated components are, in this instance, detected by a flame ionization detector (Harley, Nel and Pretorius, 1958). In this form of detector the increase in electrical conductivity of a small hydrogen flame is measured by an electrometer amplifier and displayed on a potentiometric recorder as a "peak".…”

Main gas chromatographic detectors used in brewing analytics.

“…a high sensitivity and (with the exception of a few low molecular weight compounds) will detect all substances that contain carbon. The first FID was described about the same time by Harley and Pretorious [25], and McWilliams and Dewer [26]. Hydrogen is mixed with the column eluent and burned at a small jet.…”

“…kulárních látek detekuje všechny látky s uhlíkem. Poprvé FID popsali současně Halley a Pretorious [25] a McWiliams a Dewer [26]. Vodík se směšuje s eluentem z GC kolony a hoří v malé trysce.…”

Methane in Air Quality and Automobile Exhaust Emission Standards

“…Soon after the development of the flame ionization detector 22 ' 23 a flame ionization analyzer was designed to measure total hydrocarbons. 24 Since this detector responds to carbon atoms it proved to be more sensitive than the most sophisticated infrared instrumentation for ambient air measurements and did not require the freezeout apparatus as did the mass spectrometer.…”
