Gas Chromatography/Mass Spectrometry (GC/MS)

GC/MS is considered to be the most definitive method for confirming the presence of a detected substance in urine and is approximately 100 to 1000 times more sensitive than EMIT. GC/MS is a two-step process: Gas Chromatography separates the sample into its constituent parts, while Mass Spectrometry provides the exact molecular identification of the compounds. GC/MS is utilized to confirm test results that indicate any level of a controlled substance. It is also used to screen suspicious samples: if the laboratory suspects masking agents such as adulterants, dilution through the use of detoxifiers, or a host of other sample abnormalities, GC/MS will be employed to identify the exact chemicals compounds present. This is necessary because the EMIT will only indicate whether something similar to what is being tested for is present. Abstinence is the only ways to defeat a GC/MS test.
