目前,原子吸收光谱法和电感耦合高频等离子体发射光谱法等先进分析方法已广泛用于生物医学试样中微量元素的分析测定。采用这些方法都需要把有机固体试样经过分解处理制成溶液。在现有的分解试样方法中,常用的有干灰化法、湿法消化法、低温氧等离子体灰化法、加压密封消化法等,这些方法各有优缺点。特别是生物医学试祥的特点是样品多、量少、 At present, advanced analytical methods such as atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry have been widely used in the determination of trace elements in biomedical samples. These methods require that the organic solid sample be decomposed to form a solution. Among the existing decomposition sample methods, there are commonly used dry ashing method, wet digestion method, low temperature oxygen plasma ashing method, pressurized sealing digestion method and the like, each of which has its own advantages and disadvantages. In particular, the characteristics of biomedical trial Xiang is more samples, less,
