Forensic Toxicology Analysis of Non-derivatized Drugs in Urine by Automated Solid Phase Microextraction (SPME) GCxGC-TOFMS

3. Experimental Conditions 4. Results and Discussion Comprehensive two dimensional gas chromatography in combination with time-of-flight mass spectrometry detection (GCxGC-TOFMS) was used for drugs of abuse analysis in urine without time consuming sample derivatization. Methamphetamine, cocaine, diacetylmorphine, codeine, oxycodone, ecstasy, acetylcodeine, monoacetylmorphine, hydrocodone, and L...

A New Approach for the Characterization of Organic Residues from Stone Tools Using GCGC-TOFMS

Headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) have traditionally been used, in combination with other analyses, for the chemical characterization of organic residues recovered from archaeological specimens. Recently in many life science fields, comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GCˆGC-TOFMS) has p...
