地球化学探矿要求测定的样品中微痕量元素愈来愈多,对分析的下限及精度也都有较高的要求。但是,常规的火焰原子吸收法对一些吸收线处于紫外区的元素——As、Sb、Bi等的测定灵敏度很低,这就难于满足分析要求。1969年,W·Holak首先将氢化物发生技术与原子吸收光谱法结合起来,为原子吸收光谱分析开辟了一条新的途径。十多年来,由于分析工作者的不断探索和改进,使氢化物原子吸收法扩大到砷、锑、铋、锗、锡、铅、硒、碲
Geochemical exploration requirements of the determination of trace elements in the sample more and more analysis of the lower limit and accuracy also have higher requirements. However, the conventional flame atomic absorption method for some absorption lines in the ultraviolet region of the elements - such as As, Sb, Bi, etc., the determination of sensitivity is very low, it is difficult to meet the analytical requirements. In 1969, W. Holak first combined hydride generation with atomic absorption spectroscopy, opening up a new avenue for atomic absorption spectroscopy. For more than a decade, due to continuous exploration and improvement by analytical workers, the hydride generation atomic absorption method has been extended to arsenic, antimony, bismuth, germanium, tin, lead, selenium and tellurium
