| Abstract: | A low temperature Ar_H 2 flame automatic ignition device is successfully developed recently and its application in HG_AFS analysis is introduced in this paper. The analytical features of the new system for eight hydride formation elements (As, Sb, Bi, Se, Te, Ge, Sn and Pb) including detection limits and precision are demonstrated. The effects of pre_heating temperature on sensitivity, linear range, memory effect and the mechanism of hydride formation are also discussed. |
