摘要
将库检索与目标转换因子分析相结合,利用抽象浓度的分布信息确定可能解域,其中最大可能解即为体系包含的物种。可能解域的确定大大减少了计算量。应用于严重重叠的甲苯和乙苯二组份和苯、甲苯及乙苯三组份混合体系,结果令人满意。
In this paper, a new method combining target transformation factor analysis and spectral library searching (LS) was developed for qualitative analysis of mixture from IR da- ta. At first, possible solution fields were determined from distribution of abstract concentra- tion. Then, by use of LS, the most possible solution from every field as components of the system was chosen. The method was used in actual two-component (benzene and toluene) and three-component (benzene, toluene and ethyl benzene) systems in which characteristic peaks overlapped greatly. The result was satisfactory.
