液相色谱-原子荧光联用仪(LC-AFS)测试方法探讨

Study on the Determination Method of LC-AFS

液相色谱-原子荧光联用仪(LC-AFS)主要用于砷、汞等有毒有害元素及其化合物的形态分析检测,目前尚没有LC-AFS测试的标准方法,本文对LC-AFS联用技术进行了简要概述,探讨了该仪器检出限、重复性和测量线性的测量方法,并进行了实验验证,为该类仪器的测试提供了方法,保证了仪器量值的准确性。

Liquid chromatography,atomic fluorescence combination instrument（LC-AFS） is mainly used for poisonous and harmful elements such as arsenic and mercury and its compounds of morphological analysis to detect,there is no standard method for the test of LC-AFS,in this paper,the LC-AFS technology has carried on the brief overview,the instrument detection limit are discussed,repeatability and measurement of linear measuring method,and experimental verification,provides the method of this kind of instrument for test,to ensure the accuracy of the value instrument.
