GC-MS
Gas Chromatography/Mass Spectrometry (GC-MS, GCMS or GC/MS) is an analytical method that is used to determine the composition of substances within a test sample. As the name describes, the system is composed of a gas chromatograph to separate the substances (analytes) and a mass spectrometer to identify these analytes. This is the gold standard for analysis in many fields such as forensics or petrochemical studies as GC-MS allows for the unequivocal identification of substances.

- Automated Sample Derivatization for High-Throughput Drug Testing by SAMHSA Guidelines Urine samples were analyzed according to Substance Abuse and Mental Health Service Administration guidelines for workplace drug testing.
- Breath Analysis for Disease Interrogation Breath volatomes were analyzed via GCxGC-TOFMS to demonstrate possible future of metabolomic studies.
- Forensics Analysis Workflow using EI & CI in HRTOFMS Controlled substances, such as marijuana, cocaine, heroin and methamphetamines, are commonly seized by law enforcement officials and routinely analyzed by forensic laboratories. Explore how HRTOFMS using Electron and Chemical Ionization can analyze these substances.
- Determining High-Concentration Aromatic Compounds in Gasolines (ASTM D5769) Using CG-TOFMS ASTM D5769 is a widely accepted standard method used in the petroleum industry for determination of benzene, toluene, and total aromatics in finished gasolines by GC-MS. A common difficulty encountered with this method is the concern with saturation of the ion source, which leads to nonlinearity in calibration curves, especially for the quantification of the high-concentration aromatics, such as toluene.
- Accurate Deconvolution by Exploiting Differential Expressions A set of chromatography-mass spectrometry data for multiple related samples may be considered as a tensor with spectral, retention, and experimental dimensions.
