flame ionization detector WEB:<http://homepages.onsnet.nu/%7Ealkema/html/whatisgc.html> flame ionization detector PERSON:Daniel Schober http://msi-ontology.sourceforge.net/ontology/CHROM.owl#msi_01197 FID A flame ionization detector is a GC detector that consist of a hydrogen/air flame and a collector plate which are normally heated independently of the chromatographic oven. Heating is necessary in order to prevent condensation of water generated by the flame and also to prevent any hold-up of solutes as they pass from the column to the flame. There is an electrode above the flame to collect the ions formed at a hydrogen/air flame. The number of ions hitting the collector is measured and a signal is generated. Flame ionization detectors are most widely used and generally applicable for gas chromatography and hence is used for routine and general purpose analysis. It is easy to use but destructive of the sample. gas chromatography detector metadata complete
