在食品材料的微量元素分析中。已广泛采用石墨炉原子吸收法作为测试手段,固体进样技术的发展摆脱了繁琐的样品消解过程,从而在很大程度上克服了长期以来令人头痛的化学沾污问题。然而,由于直接固体进样技术称样量小,它要求样品具有高度的
In the analysis of trace elements in food materials. Graphite furnace atomic absorption spectrometry has been widely used as a test method. The development of solid-state sampling technology has got rid of the tedious sample digestion process and thus largely overcomes the long-awaited chemical contamination problem. However, because of the small sample size required for direct solid injections, it requires that the sample be highly oriented
