| Abstract: | Some characteristics of the novel hydride generation systemmovable reduction bed hydride generator (MRBHG) is reported in this paper. Besides accomplishing the hydride generation at microliter sample volume without the need for an external addition of acid and use of a gasliquid separator, interferences among hydride forming elements are also greatly reduced in this system. The similar hydride generation efficiency for different valency and species of As and Se is obtained. The hydride forming elements in alloy steel and tea samples were determined by ICPAES with MRBHG system. The recoveries of standard addition for As and Se in alloy steels and a Chinese tea sample are 937% and 984% respectively.\=\= |
