摘要
作者根据氢化物原位富集分析方法,研制了一台原子吸收用的石墨炉自动进样器。该仪器与原子吸收仪相配合,适于分析As,Se等能形成氢化物的诸元素。
A Model HG-100 automatic sampler is designed for the determination of hydrideforming dements by hydride generation-graphite furnace atomic absorption spectrometry with in situ concentration of hydrides on the Pd-Coated graphite tube. This technique gives 20～30 folds obtained by conventional HG-AAS or HG-AFS, and can be applied to determine hydride-forming dements at 10^(-11) level.
