Solid Phase Extraction Gas Chromatography Triple Quadrupole Tandem Mass Spectrometry Determination Propofol and Phenoxyethanol in Aquatic Products
Objective:To establish a method for the determination of propofol and phenoxyethanol residues in aquatic products by solid phase extraction-gas chromatography-triple quadrupole tandem mass spectrometry.Method:After extraction,the samples were purified by solid phase extraction and separated by DB-WAXUI chromatographic column.The detection mode was electron bombardment ion source and dynamic multi-reaction monitoring.Result:The linear detection range of the two anesthetic standards was 10～500 ng·mL-1,and the detection limit was 0.005 mg·kg-l.The recovery rate was 87.5%～96.3%,and the relative standard deviation was 0.9%～7.3%.Conclusion:This method can meet the needs of detection of anesthetic residues in aquatic products.
