HYDRIDE GENERATION ANALYSIS METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing disturbance of transition metal and rapidly and accurately measuring a target element in liquid chromatographic separation-hydride generation analysis for a sample containing arsenic, antimony, selenium, tin, or the like.SOLUTION: A hydride generation analysis method controls so that feeding of boron hydride sodium solution is stopped by using switching means within a prescribed period while feeding of acid solution to a sample after the sample passes through a separation column 4.
