摘　　要：介绍了V(正己烷)∶V(甲苯)=1∶1溶液中8种有机氯农药混合校准标准样品的研制方法。校准标准样品采用称量法制备,采用气相色谱/电子捕获检测器内标法进行均匀性检验和稳定性监测。评估研制过程中产生的不确定度,合成为校准标准样品的不确定度。研究结果表明,V(正己烷)∶V(甲苯)=1∶1溶液中8种有机氯农药混合校准标准样品均匀性和稳定性良好,量值准确,可用于环境监测和科学研究工作。The development technique of the calibration certi-fied reference material（CRM） of 8 organic chlorine pesticides （OCPs） in n-hexane and toluene （ V： V = 1 ： 1 ） was presen- ted. The CRM was prepared with gravimetric method. The homogeneity testing and stability monitoring of the CRM were done hy GC/ECD. The uncertainty was analyzed and com-bined in the CRM study. The results of the research show that the CRM is homogenous,stable and accurate. It may be used in the environmental monitoring and other studies.
