Q: What is GC/MS? A: GC/MS is the abbreviation for gas chromatography/mass spectrometry, the testing methodology LabCorp uses to confirm presumptive positive drug screen specimens. GC/MS provides identification of the molecule(s) based on characteristic fragmentation patterns at specific retention times. GC/MS is a tandem technology, utilizing a gas chromatograph coupled to a mass spectrometer. Q: Why are screening and confirmation cut-off levels different? A: Simply stated, screening and confirmation testing are performed using different testing methodologies that precipitate different cut-off levels.
Gas Chromatography (GC or GLC) is a commonly used analytic technique in many research and industrial laboratories for quality control as well as identification and quantitation of compounds in a mixture.he lower the boiling point is, the shorter retention time usually is because the compound will spent more time in the gas phase. That is one of the main reasons why low boiling solvents (i.e., diethyl ether, dichloromethane) are used as solvents to dissolve the sample.
