A method of analysis As, Sb, Bi, Se, Te, Sn which produce hydride easily by coupling gas-propelled flow injection hydride generation (HG) system with inductively coupled plasma mass spectrometer (ICP-MS) using our laboratory designed sprayer as the interface is described. Experiments of several kinds of agents and nickel matrix were carried out to investigate the influence on signal response of hydride generation. And finally, we realize on-line determination of As, Sb, Bi, Se, Te, Sn in pure nickel by HG-I...
