Determination of oxaziclomefone residues in rices by QuEChERS-UPLC-MS/MS
A method for the determination of oxaziclomefone residues in rices was developed by UPLC-MS/MS.The analytes were purified by QuEChERS,and quantified by an external standard method.The results indicated that the correlation coefficients of the method were more than 0.999.The recoveries of oxaziclomefone were 81％-95％at the adding level of 0.002-1.0 mg/kg,the relative standard deviations ranged from 1.1％to 9.8％,and the limit of quantitation in rices was 0.002 mg/kg.The method was suitable for rapid screening and quantitative analysis of oxaziclomefone in rices with convenient,high precision and efficient.
