Journal ArticleDOI
Simple extractive derivatization of methamphetamine and its metabolites in biological materials with Extrelut columns for their GC-MS determination
TL;DR: A simple, extractive heptafluoro-n-butyrylation with Extrelut columns was devised and AMP, MAMP, and HMAMP could be determined in an actual forensic case study.
Journal ArticleDOI

TL;DR: Even though high caffeine concentrations were found in the systemic organs, no caffeine-related pathological changes were detected in the blood, urine and main organs in a fatal caffeine intoxication case.
Journal ArticleDOI
Simultaneous determination of 13 amphetamine related drugs in human whole blood using an enhanced polymer column and gas chromatography-mass spectrometry.
TL;DR: A simple method for simultaneous identification and quantification of 13 amphetamine related drugs in human whole blood and should be most useful for confirmation of positive immunoassay results for amphetamines and related drugs.
Journal ArticleDOI
Rapid determination of cyanide in human plasma and urine by gas chromatography-mass spectrometry with two-step derivatization.
TL;DR: This sensitive and less time consuming method based on solid-supported liquid-liquid extraction and gas chromatography-mass spectrometry with two-step derivatization for determination of CN in plasma and urine was successfully applied to the analysis of blood sample and urine sample collected from a victim who died as a result of ingestion of potassium cyanide.
Journal ArticleDOI
Toxicological and histopathological analysis of a patient who died nine days after a single intravenous dose of methamphetamine: a case report.
TL;DR: This case suggests that the postmortem diagnosis of MA poisoning in patients who survive for relatively longer periods after drug injection should include toxicological hair analysis in combination with histopathological and postmortem physiochemical examination.
