Gas chromatography ion detector
Many gas chromatograph detectors are ion detectors with varying methods of ionizing the components eluting from the gas chromatograph's column. discharge ionization detector (PDD) -- similar to a Discharge ionization detector (DID), but uses a different sort of spark References See also Gas Chromatograph wikipedia.org

How can I describe running a solution four times through a chromatography unit (in an instruction)? I'm translating a document from Russian: > The mean retention time for the first four injections of RNase should be ...
I would say simply: > repeat the chromatography four times or less formal, but quite acceptable: > re-run the column (or whatever it is) four times This puts the emphasis on the process. But I’m not exactly sure what’s happening. You have four injections of RNAase. If they are not right are you repe...

Halimeter
The small size, simplicity of use, and price (relative to gas chromatograph) of the Halimeter made it popular among dentists seeking to diagnose and treat More recently, the portable gas chromatograph, "OralChroma" has been recommended in the diagnosis of halitosis, as the Halimeter does not detect dimethyl wikipedia.org

Perfluorocarbon tracer
The sample is then admitted to a gas chromatograph. This splits up the different PFTs, so a concentration value can be determined for each one. An alternative set up; the chromatograph can be omitted, and the different PFTs determined from their different masses in the mass spectrum. wikipedia.org
