【摘要】 <正> 近年来用分光光度法结合电子计算机,对多组分混合物不经分离进行测定的方法发展较快。在无机多组分体系方面,有以线性规划法分析稀土元素混合物和用矩阵方法分析锰、锌混合物的研究。对有机多组分体系作者曾对三个相互干扰组分:阿斯匹林、非那西丁和咖啡因用线性规划法及坐标轮换法进行紫外光谱计算分析;胡鑫尧等则对此体系作了红外光谱计算分析研究,并提出了非线性规划更多还原

【Abstract】 The simultaneous determination of four interfering component systems by infrared spectrometry has been investigated. A modified matrix is used for computing analysis incorporated with calibration of molecular interactions and deviation on wave length selection, number of standard mixtures used and other computing models is presented. The new method has been successfully used for the simultaneous determination of amidopyrine, phenacetin, caffeine and phenobarbital. It is a simple and accurate method for the infrared spectrometric computing analysis of multicomponents systems.更多还原
