Outline of Final Research Achievements

In the investigation of the cause of death in forensic toxicology, analysis of the drug is important. We have examined the development of screening methods for searching for a wide variety of drugs. Postmortem samples, since often contains a large amount of lipids, removal of lipids were mainly studied. Preparation of postmortem sample was studied on ion pair acetonitrile extraction, lipid removal by a specific filter and by organic solvent washing, and ion exchange purification. Fast GC-MS by use of two connected column, was able to apply to the measurement of rapid and sensitive. Except highly denatured sample, the methods developed in this study were feasible for practical applications. In this sample preparation, a wide range of from lipophilic drugs to hydrophilic drugs can be measured by a combination of GC-MS and LC-MS / MS.
