Mass Spectrometric Detection and Analysis Method

Abstract

The present invention provides a mass spectrometric detection and analysis method, comprising the steps of: selecting, as a perturbation condition, one or more parameters of a mass spectrometer during detection, setting a set of different numeric values for the perturbation condition, detecting by the mass spectrometer a substance to be detected under the different numeric values of the perturbation condition to obtain a set of mass spectrometric data; calculating the set of obtained mass spectrometric data by an entropy minimization algorithm to obtain independent ions in the mass spectrometric data and kinetic processes thereof; and performing mass spectrometric analysis on the basis of the obtained independent ions and kinetic processes thereof. The method of the present invention can quickly and accurately perform qualitative analysis on the substances to be detected, especially on substances that are difficult to distinguish with existing mass spectrometric techniques such as isomers and homologues. The method of the present invention can also perform analysis by the difference between the kinetic processes and thereby determine the nature of such substances. The method of the present invention has a very broad application prospect due to its simple operation and accurate results of analysis.
