Spectrometry testing
WebThe most sophisticated drug-testing approach is gas chromatography coupled with mass spectrometry (GC/MS), which is regarded as a "gold standard"; it is used in confirmatory testing. Typically, GC/MS is preceded by a rapid immunoassay method to eliminate the majority of the "negative" samples. Despite the existence of sophisticated drug-testing ... WebLiquid Chromatography Mass Spectrometry (LC-MS) Identify quantify unknown compounds even in complex matrices with our precision LC-MS systems. Ion Chromatography Mass Spectrometry (IC-MS) Employ IC-MS when you need to increase your IC detection capability, such as to detect and quantify unexpected co-elutions or confirm trace components.
