Separation and identification of trifluralin metabolites by open-tubular liquid chromatography/negative chemical ionization mass spectrometry.
The utility of combined open-tubular liquid chromatography/negative ion chemical ionization (NCI) mass spectrometry for the separation and analysis of trifluralin, a commonly used pre-emergence herbicide, and seven of its metabolites has been demonstrated. The NCI mass spectra for these compounds are reported. Some of the NCI mass spectra were obtained from as little as 50 pg of analyte.
