Scope
The main technical content is as follows: 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 the target substance is eluted using an ammonia-methanol solution. The target substance is detected by a liquid chromatography-triple quadrupole mass spectrometer. The target compound in the sample is identified based on its retention time, fragment ions, and their mass-to-charge ratio and abundance ratio. The quantification is performed using the isotope dilution method.
