Quantitation of diethylene glycol and its metabolites by gas chromatography mass spectrometry or ion chromatography mass spectrometry in rat and human biological samples.

abstract：:A sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for the quantitation of oxymorphone (OM) in human whole blood and liver. Sample preparation was done by solid-phase extraction, using deuterated OM as the internal standard. Separation was achieved using a Waters Aquity UPLC ...
