A highly selective and sensitive liquid chromatography–tandem mass spectrometry (LC MS/MS) method was developed for the quantification of metronidazole (MTZ) in human feces. The analyte was recovered from feces after liquid–liquid extraction with ethyl acetate and separated on Waters Symmetry® C18 (100 × 4.6 mm, 5μm) column using 0.1% formic acid in water and acetonitrile (40:60, v/v) as the mobile...
A highly sensitive, selective and rugged method has been described for the quantification of metronidazole (MTZ) in human plasma by liquid chromatography–tandem mass spectrometry using metronidazole‐d4 as the internal standard (IS). The analyte and the IS were extracted from 100 μL plasma by liquid–liquid extraction. The clear samples obtained were chromatographed on an ACE C18 (100 × 4.6 mm, 5 μm)...
