"[Saliva] can be collected directly--and in public--from an individual, so the sample cannot be altered," says Hosken. The sample is then placed into what's called a GC/MS GC/MS Gas Chromatograph/Mass Spectrometer GC/MS Gas Chromatograph/Mass Spectrometry GC/MS Gas Chromatograph/Mass Spectrograph instrument. This device identifies drug chemicals based on their mass. The data show up on a computer screen in roughly 15 minutes. |
