mass selective detector mass selective detector PERSON:Daniel Schober A mass selective detector is a GC detector that uses mass spectrometry. It is based upon the ionization of solute molecules in the ion source and the separation of the ions generated on the basis of their mass/charge ratio by an analyzer unit. This may be a magnetic sector analyzer, a quadruple mass filter, or an ion trap. Ions are detected by a dynode electron multiplier. mass spectrometry detector WEB:<http://homepages.onsnet.nu/%7Ealkema/html/whatisgc.html> http://msi-ontology.sourceforge.net/ontology/CHROM.owl#msi_01198 gas chromatography detector metadata complete
