A Novel Hydride Generation Technique—— Movable Reduction Bed Hydride Generator Ⅰ. The Configuration and Characteristic of the Movable Reduction Bed Hydride Generator

发展了一种新型的氢化物发生技术———可移动还原床氢化物发生器，可以实现微升级样品的分析而不需要对样品进行酸化和使用气－液分离器。给出了装置的结构、操作，试验并优化了固体还原剂与有机酸的质量配比、反应腔体体积、进样量等反应条件。该技术易于实现自动化，可作为液相色谱、毛细管电泳和其他色谱分离技术与光谱检测技术之间的接口。

A novel hydride generation system termed “movable reduction bed hydride generator” has been developed in this work. It will accomplish the hydride generation at micro liter sample volume without the need for an external addition of acid, and the use of a gas liquid separator. The technique may offer a possibility of automatic operation, as well be used as an interface for liquid chromatography(LC), capillary electrophoresis(CE) and other chromatograph.
