A quantitative analysis was developed for the determination of cocaine, benzoylecgonine, and cocaethylene in oral fluid using liquid chromatography-tandem mass spectrometry. After internal(More)
We investigated the corneal precipitate of a 6-year-old boy with vernal keratoconjunctivitis (VKC), treated with topical ofloxacin 0.3% eyedrops. Because of the extremely small sample amount (corneal(More)
A liquid chromatographic mass spectrometric strategy for systematic toxicological analysis (STA) is presented using the automatic 'on-the-fly' single mass spectrometry mode to tandem mass(More)
We present a liquid chromatographic-mass spectrometric assay for the simultaneous determination of sulfadoxine and pyrimethamine in human plasma samples. Sample clean-up was achieved by adding(More)
The development of a LC-MS/MS general unknown screening procedure for toxicologically relevant substances in blood samples by means of information-dependent acquisition on a Q-TOF is reported. IDA is(More)
A solid-phase extraction (SPE) method was optimized to suit the particular demands of an information-dependent acquisition LC-MS-MS procedure for general unknown screening in a forensic toxicology(More)
An entire series of SPE sorbents, classified into three different categories (apolar, mixed-mode and polymeric) was evaluated for sample preparation of a data-dependent LC-MS-MS "general unknown"(More)
