Title:
SAMPLE DESORPTION AND IONIZATION DEVICE, AND MASS SPECTROMETER AND ANALYSIS METHOD APPLYING SAME
Document Type and Number:
WIPO Patent Application WO/2019/205805
Kind Code:
A1
Abstract:
The present invention provides a sample desorption and ionization device, and a mass spectrometer and an analysis method. The device comprises: a heating desorption device, located in a first gas pressure region, and used for bearing and heating a sample, so that an analyte to be analyzed in the sample is desorbed from the sample under the effect of heating and then enters the first gas pressure region; a vacuum interface component, connecting the first gas pressure region and a second gas pressure region, and used for enabling the analyte to be analyzed to enter the second gas pressure region from the first gas pressure region under the driving of a gas flow; and a soft ionization source, used for converting gas molecules in the second gas pressure region into active gas molecules, so that the analyte to be analyzed that enters the second gas pressure region interacts with the active gas molecules to implement soft ionization. According to the present invention, the introduction efficiency of ions after ionization of the analyte in mass spectrometric analysis can be significantly improved and the applicable range of the analyte can be expanded.
