          摘要:

          標準方法驗證是檢驗檢測實驗室質量管理過程中的重要一環,是保障檢驗檢測數據準確性的基礎。本文建立了超高效液相色譜三重四級桿質譜聯用儀測定水體中磺胺類藥物殘留量的方法,從標準曲線、線性范圍、定量限、精密度及方法回收率幾方面進行方法驗證,并對本方法的實驗關鍵點進行了分析優化。結果表明:17種磺胺類藥物在5.0 ng/mL~50 ng/mL濃度范圍內線性良好,校準曲線相關系數r2值均大于0.997,該方法的檢出限為0.038 ng/mL,3個加標水平的平均回收率在74.6%~105.6%之間,相對標準偏差0.89%~12.89%。該方法的建立,可為監控水產養殖過程中磺胺類藥物的使用情況提供技術依據。

          Abstract:

          Standard method validation is an important part of the quality management process in inspection and testing laboratories, and is the foundation for ensuring the accuracy of inspection and testing data. In this study, a method for determination of sulfonamides residues in water by UPLC-MS/MS was established.Verify the method from standard curve, linear range,quantification limit, precision, and method recovery rate. And the key experimental points of this method were analyzed and optimized. 17 kinds of sulfonamides have good linearity within the concentration range of 5.0 ng/mL-50 ng/mL. The correlation coefficient of calibration curve were more than 0.997. The detection limit of this method was 0.038 ng/mL. The average recovery rates of three spiked levels range from 74.6% to 105.6%, and the relative standard deviations were 0.89%~12.89%. The method could be used for quantitative determination of sulfonamides residues in water from aquaculture environment..
