小波分析和人工神经网络方法用于重叠色谱峰的解析
Resolution of overlapping chromatograms by wavelet analysisand artificial neural network
【摘要】 将神经网络与小波分析相结合,提出一种利用小波变换提取重叠色谱峰信息,再用人工神经网络解析的方法,为色谱峰重叠难于分开物质的测定提供一种方法,提高了色谱分析的准确度,并将此方法应用于高效液相色谱中,建立了混合体系中3,4-二甲酚和2,5-二甲酚同时测定的新化学计量学方法.
【Abstract】 In this paper,BP-ANN and WT are combined to set up a new chemometric method,by which useful information is extracted and then is calculated by artificial neural network.The method has been applied to the simultaneous determination of 3,4-dimethylphenol and 2,5-dimethylphenol for high performance liquid chromatograph.
