【摘要】 基于吸光度联立方程组并选择一组合适的系数进行线性组合,提出了多波长吸光度数据线性组合分光光度法,得到的吸光度与被分析物浓度成正比,而与另一干扰物无关,从而消除干扰,本法能改善选择性与准确度,并具有测量波长较多与计算简便等特点,可用于两组分的单一或同时测定,已用于盐酸氯丙嗪与盐酸异丙嗪复方药物、雷琐辛复方涂剂等分析。更多还原

【Abstract】 The linear combination of multi-wavelength data (absorbance) is developed as a new computational spectrophotometry to improve the selectivity and accuracy, based on the combination of simultaneous equations with a set of proper coefficients. The absorbance obtained is in proportion to the concentration of the analyzed compounds and independent of the interferents, thus the in terference’ can be removed. The proposed method , which has the advantage for determining multi-wavelength data with simpler computation and can be used in single or simultaneous measurement, has been applied to the analysis of compound pharmaceutical preparations.更多还原
