基于色谱数据的卷烟质量稳定性评价方法OACSTPCD

gas chromatography/mass spectrometry analysis of mainstream flue gas composition is a conventional effective technology,for the evaluation of mainstream flue gas stability,need first to different batches of different retention time of mass spectrum and standard mass spectrum qualitative,determine the active component,then according to the peak area response of the active component situation,using Angle cosine,correlation coefficient,European distance,similarity evaluation,can not directly compare the original chromatogram data.And for the mainstream flue gas samples,its composition is very complex,difficult to accurately qualitative and quantitative,human consumption is large,the efficiency is not high.In this paper,using the Fourier transform method,we transform the map into frequency domain data and evaluate the similarity of the sample,and its objectivity,reliability and timeliness are better than the traditional method.
