Forensic Application of LC-MS and GCMS.
LC-MS is used for the identification of dyes extracted from textile fibers and the utility of the method for forensic trace analysis is demonstrated. The technique is shown to provide a high degree of chemical structural information,making dye identification highly specific in comparison to optical and/or chromatographic methods of dye analysis.
GC-MS-MS method for determining trace concentrations of gammahydroxybutyrate (GHB) in blood and urine has been developed. Multiplereaction monitoring was used to detect parent and daughter ions of GHB,233 and 147.
