Method, system, terminal and storage medium for regulating an electrospray ion source of a mass spectrometer

Abstract

The application relates to the technical field of material analysis, and particularly discloses a method and system for regulating an electrospray ion source of a mass spectrometer, a terminal, and a storage medium. The method comprises the following steps: performing feature-level fusion on a multivariate isomer monitoring data set of the electrospray ion source to obtain a digitized state feature vector; periodically dividing the digitized state feature vector to analyze the change trend of a current period state feature vector and obtain a predicted numerical value interval; performing multidimensional compound logic comparison on the current period state feature vector and the predicted numerical value interval to obtain an enhanced state evaluation result; performing state tracing attribution on the current period state feature vector to obtain a core feature dimension and a corresponding change trend, and mapping the core feature dimension and the corresponding change trend to a preset regulation rule library to obtain a working state adjustment parameter set; and encoding the working state adjustment parameter set into a regulation instruction. The application can improve the regulation efficiency of the electrospray ion source of the mass spectrometer.
