Scope

Main technical content: The water sample is enriched and purified by a weak ion exchange solid phase extraction column. First, methanol is used to remove impurities in the enrichment column, and then an ammonia-methanol solution is used to rinse to obtain the target substance. The target substance is detected by a liquid chromatography triple quadrupole mass spectrometer. It is qualitatively identified based on the retention time, fragment ions of the target compound in the sample, and their mass-to-charge ratio and abundance ratio. It is quantitatively determined by the isotope dilution method
