Determination of nonderivatized para-hydroxylated metabolites of diazepam in biological fluids with a GC Megabore column system.
A method was developed using gas chromatography (GC) and a Megabore column system capable of simultaneous detection of diazepam, N-desmethyldiazepam, temazepam, oxazepam, and their para-hydroxylated metabolites. This method does not require derivatization of para-hydroxylated metabolites. Standard curves for pure reference compounds were linear, with the minimum detectable concentration of diazepam and its metabolites as low as 0.13 ng/injection.
