| 摘 要： | 基于谱图叠加和小波分析技术,提出了一种新的信号处理方法--谱图叠加法.该法可以有效地提高色谱信噪比,使只能定性分析的信号达到定量分析的目的.应用此法处理对氨基苯甲酸毛细管电泳信号,信噪比从3提升至11,其结果令人满意.

| Abstract: | A new method was presented to deal with chromatography weak signals .Chart adding method and wavelet technology were applied to improve the SNR .The signals which can only be qualitatively analyzed now can be quantitatively analyzed by using proposed method. In the present work the method was applied to capillary electrophoresis signals of p-aminobenzoic acid, the result was satisfied that the SNR was improved from 3 to 11. |
