Journal ArticleDOI
GC-PCI-MS/MS and LC-ESI-MS/MS databases for the detection of 104 psychotropic compounds (synthetic cannabinoids, synthetic cathinones, phenethylamine derivatives).
Brian Waters,Natsuki Ikematsu,Kenji Hara,Hiroshi Fujii,Tomoko Tokuyasu,Mio Takayama,Aya Matsusue,Masayuki Kashiwagi,Shin-ichi Kubo +8 more
TL;DR: Using a detection method that has been rarely utilized to analyze these types of compounds, gas chromatography with positive chemical ionization and tandem mass spectrometry (GC-PCI-MS/MS), 5 psychotropic compounds were detected in an actual forensic autopsy case.
Journal ArticleDOI
High throughput chiral analysis of urinary amphetamines by GC-MS using a short narrow-bore capillary column
TL;DR: Very rapid and simultaneous chiral analysis of urinary amphetamine-type stimulants (ATSs) using gas chromatography-mass spectrometry (GC-MS) with a simple procedure and all chiral isomers of the ATSs targeted in this study were chromatographically distinguishable within 5 min.
Journal ArticleDOI
Development of a preparation method to produce a single sample that can be applied to both LC–MS/MS and GC–MS for the screening of postmortem specimens
Kenji Hara,Brian Waters,Natsuki Ikematsu,Tomoko Tokuyasu,Hiroshi Fujii,Mio Takayama,Aya Matsusue,Masayuki Kashiwagi,Shin-ichi Kubo +8 more
TL;DR: Simple and efficient extraction methods have been developed for the screening of a wide array of drugs in postmortem autopsy specimens that could easily be incorporated into a forensic laboratory's daily routine for screening many different compounds from postmortem samples.
Journal ArticleDOI
Two simple methods for enantiomeric analyses of urinary amphetamines by GC/MS using deuterium-labeled l-amphetamines as internal standards
Zhao Liu,Kenji Hara,Seiichi Kashimura,Junting Liu,Junting Liu,Hiroshi Fujii,Masayuki Kashiwagi,Aya Miyoshi,Tomoko Yanai,Mitsuyoshi Kageura +9 more
TL;DR: In this article, two simple methods for enantiomeric analyses of amphetamines in urine by gas chromatography-mass spectrometry (GC-MS) using l-amphetamine-d 3 and l-methamphetamined 6 as internal standards are presented.
Journal ArticleDOI
Rapid GC–MS analysis of methamphetamine and its metabolites in urine—application of a short narrow-bore capillary column to GC–MS
Hiroshi Fujii,Kenji Hara,Seiichi Kashimura,Mitsuyoshi Kageura,Masayuki Kashiwagi,Aya Miyoshi,Sachiko Ikeda +6 more
TL;DR: The results indicate the possibility of rapid analysis using a conventional GC-MS with a short NBC at a relatively low inlet pressure, and a urine sample from a drug-abuse suspect was analyzed.
