GUO Xiaowei and GUO Xuming(Northwest Research institute of Geology CNNC, 710054 Xi'an)
A new hydride--generation sample introduction technique has been proposed and described in this paper. The technique, which is called intermittent flow method is a hybrid of flow injection and continuous flow method. Some unique advantages of using intermittent flow technique including less cross contamination,simple instrument setup, flexible sampling amounts and low running cost are discussed.This technique has been successfully applied to hydride generation AAS/AFS.
