使用多元线性回归方法，处理电荷耦合器件多波长荧光检测毛细管电泳装置得到的三维电泳图，将在电泳时未达到有效分离、重叠严重的混合物电泳峰，分解成单个组分的电泳峰，可进行有效的定性定量分析。该法用于电泳峰完全重叠的混合罗丹明荧光染料样品，结果令人满意。 Using multiple linear regression method to deal with the three-dimensional electrophoresis images obtained by the multi-wavelength fluorescence detection capillary electrophoresis device of the charge-coupled device, the electrophoretic peak which is not effectively separated during the electrophoresis, and the mixture of the heavy overlapping peaks are decomposed into electrophoresis peaks of individual components can be performed Effective qualitative and quantitative analysis. The method for the complete overlap of electrophoresis peak mixed rhodamine fluorescent dye samples, the results were satisfactory.
