gas generator PERSON:Daniel Schober gas generator http://msi-ontology.sourceforge.net/ontology/CHROM.owl#msi_01033 gas chromatography equipment WEB:<http://www.chromatography-online.org/GC/Gas-Supplies/Pure-Air-Generators./rs5.html> An instrument that generates gases for use with the gas chromatograph. Previously gas was obtained from gas tanks or gas cylinders. However, over the past decade the use of gas generators have become more popular as it avoids having gases at high pressure in the laboratory which is perceived by some as potentially dangerous. In addition, the use of a hydrogen generator avoids the use of a cylinder of hydrogen at high pressure which is also perceived by some as a serious fire hazard despite the fact that they have been used in laboratories, quite safely for nearly a century. gas chromatography equipment metadata complete
