| Abstract: | A multi-residue analysis method for the simultaneous quantitative determination of 12 benzimidazoles(BZs) in milk has been developed and validated by liquid chromatography tandem mass spectrometry.The samples were extracted and purified with the optimized QuEChERS method.In this method,acetonitrile with 0.5% acetic acid were used as an extractant.PSA were scavenging material.The liquid chromatographic separation was performed on a reversed-phase C18 column with gradient elution using a mobile phase consisti... |
