Forensics
Forensic scientists often use gas chromatography to determine the presence of illegal substances in subjects, analyze emerging designer drugs, test blood or fibers from a crime scene, and detect possible residues left by explosives or accelerants.
Known advantages of VUV Spectroscopy
- Provides unambiguous identification of isomers, which are difficult to characterize by mass spectrometry (MS)
- Non-destructive detection that complements MS
- Orthogonal technique for confirming compound identity
- Peer reviewed drug of abuse data shows quantitative results in the low nanogram range
- Provides compound class information for closely related unknown compounds
- Software deconvolution of analyte co-elution allows short GC chromatographic compression
- Easy to understand analysis by Beer-Lambert Law (same principle used in UV-Vis spectroscopy)
