摘要: 建立了高效液相色谱-三重四极杆质谱测定克氏原鳌虾中多菌灵的新方法。样品在碱性条件下经乙酸乙酯提取，离心，上清液经旋转蒸发浓缩并复溶后采用混合型阳离子（MCX）萃取小柱富集净化。以乙腈和水为流动相，采用C18色谱柱进行梯度洗脱分离。在电喷雾正离子源下，采用多反应监测模式检测。结果表明：多菌灵在0.5~50.0 μg/L范围内线性关系良好，相关系数（r²）为0.9985。多菌灵的检出限和定量限分别为0.25 μg/kg和0.50 μg/kg。当加标水平为0.5、1.0、5.0和50.0 μg/kg时，加标回收率为83.9%~105.5%，相对标准偏差为1.1%~3.2%（n=6）。该方法能简单、有效地检测出克氏原鳌虾中多菌灵的残留量，且稳定性好，结果可靠。

Abstract: A novel method based on high performance liquid chromatography-triple quadrupole mass spectrometry (HPLC-MS/MS) was established for the determination of carbendazim in Procambarus clarkii. The sample was extracted by ethyl acetate under alkaline conditions and centrifuged. The supernatant was concentrated by rotary evaporation, redissolved, and then enriched and purified on a mixed-mode cation exchange solid phase extraction column (MCX). A C18 column was used with acetonitrile and water as mobile phases in a gradient elution. Ionization was performed using an electrospray positive ion source (ESI⁺), and detection was achieved by MS/MS in multiple reaction monitoring (MRM) mode. The linearity for carbendazim was good in the range of 0.5-50.0 μg/L; the linear equation was y=0.19988x+0.01842; and the correlation coefficient (r²) was 0.9985. The limit of detection (LOD) and limit of quantification (LOQ) were 0.25 μg/kg and 0.50 μg/kg, respectively. At spiked levels of 0.5, 1.0, 5.0, and 50.0 μg/kg, the recoveries ranged from 83.9% to 105.5%, and the relative standard deviation ranged from 1.1% to 3.2%. This method is simple and effective for the determination of carbendazim residues in P. clarkii.
