A rapid and accurate gas chromatographic (GC) method is described for the determination of chloramphenicol, thiamphenicol and their metabolites excreted in human urine. These excretions were pre-treated with diazomethane and N,O-bis(trimethylsilyl)acetamide, so that they could be easily subjected to

Organic acidurias are a wide group of inherited metabolic diseases, sometimes with acute neonatal symptoms and life risk in the newborn. The clinical features are often not specific, but the pattern of urinary organic acids is diagnostic. Correct identification of metabolites and timely response are
The gas chromatographic/mass spectrometric characteristics of 26 congeners of polychlorinated dibenzofurans, previously characterized by specific synthetic routes and by standard spectroscopic techniques, have been evaluated. The electron impact mass spectra are not particularly isomer-specific, tho
