【摘要】 探索了一种测量多组分样品而无须化学分离的直接分光光度法。报告了“吸收谱的计算机解谱分析法(CRAAS)”。经典的分光光度法是根据一个或几个特征峰的吸收谱分析样品。但CRAAS法中,对全波段吸收谱作数理统计分析,所以,CRAAS法精度高,分辨率也高,而且它不受不同吸收峰之间彼此重叠的于扰,只要两种物质的吸收谱形状不一样,尽管两个特征峰可能严重重叠,它们的浓度仍能被计算出。分析精度约为±5％。更多还原

【Abstract】 A spectrophotometry has been developed which can directly determine a multi-component sample by spectrophotometry without any chemical separation. CRAAS (Computer Resolution Analysis of Absorption Spectrum) has been created. It is different from the previous spectrophotometry depending on only one or several special absorption peak. The CRAAS deals with the whole region of absorption spectrum by mathematical statistics. So CRAAS has higher accuracy, stronger power and very high resolution. The trouble comes from overlap of different spectrum in each other has been solved because CRAAS depends on the whole spectrum. As long as two spectra have different shape, their concentrations can be determinated even their special absorption peaks are seriously overlapped. The accuracy is about +5%.更多还原
