Diesel component analysis method and device based on comprehensive two-dimensional gas chromatography-mass spectrometer

Abstract

The invention relates to the technical field of petrochemical engineering analysis and detection, in particular to a diesel component analysis method and device based on a comprehensive two-dimensional gas chromatography-mass spectrometer.The method comprises the steps that a diesel sample is pretreated; testing the pretreated diesel oil sample by using a comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometer to obtain a test spectrogram; integral processing and feature region division processing are carried out on the test spectrogram, substance information corresponding to all components contained in the diesel oil sample to be analyzed is obtained, and the feature region division processing is that preliminary segmentation and fine segmentation processing are carried out according to feature differences corresponding to all the components. According to the method, data processing logic can be constructed into a script or an application which is automatically executed by electronic equipment, interference factors in manual analysis and identification errors of analysis of different people are effectively reduced, rapid, comprehensive and quantitative analysis of complex components in diesel oil is realized, the analysis efficiency is improved, and the analysis cost and manual analysis errors are reduced.
