A new hydride generation system, 'movable reduction bed hydride genera
tor' has been developed which accomplishes hydride generation at micro
liter sample volume without the need for an external addition of acid,
or the use of a gas-liquid separator. Interferences among hydride for
ming elements have been greatly reduced. The technique may offer a pos
sibility for automatic operation, and could be used as an interface fo
r LC, CE and other chromatographic techniques. The recoveries of As, S
e and Sb by standard addition from a Chinese tea are 81.1(+/-2.7%), 10
2.6 (+/-3.4%) and 94.1% (+/-4.1%), respectively.
