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干扰,只要两种物质的吸收谱形状不一样,尽
A direct spectrophotometric method for measuring multicomponent samples without chemical separation was explored. Reported “computerized spectrum analysis of absorption spectra (CRAAS).” Classic spectrophotometry is based on the absorption spectrum of one or more characteristic peaks. However, in the CRAAS method, the full-band absorption spectrum is subjected to mathematical statistical analysis. Therefore, the CRAAS method has high precision and high resolution, and it is free from the interference between different absorption peaks as long as the absorption spectrum shapes of the two substances are different Do it
