Movable reduction bed hydride generator coupled with inductively coupled plasma optical emission spectrometry for the determination of some hydride forming elements

A new hydride generation system, 'movable reduction bed hydride generator' has been developed which accomplishes hydride generation at microliter sample volume without the need for an external addition of acid, or the use of a gas-liquid separator. Interferences among hydride forming elements have been greatly reduced. The technique may offer a possibility for automatic operation, and could be used as an interface for LC, CE and other chromatographic techniques. The recoveries of As, Se and Sb by standard addition from a Chinese tea are 81.1(+/-2.7%), 102.6 (+/-3.4%) and 94.1% (+/-4.1%), respectively.
