Gas Chromatography-Mass Spectrometer (GC/MS): In Scientific Evidence, Even ‘Gold Standard’ Techniques Have Limitations

View this Resource

by Joanna Gin and Edward Imwinkelreid. UC Davis Legal Studies Research Paper, available for free download. Like nuclear DNA testing, GC/MS analysis has important limitations. Courts should not assume it is a nearly infallible technique. When GC/MS is used in drug testing, the court must inquire as to the mode of analysis: full scan, selective ion reliance, or selective ion monitoring. When GC/MS is employed to identify ignitable liquids in arson investigations, the court should inquire as to the condition of the sample tested: Has it been subjected to weathering, microbial degradation, or pyrolysis?
