Abstract

The present disclosure provides a sample desorption ionization device and analysis method for a mass spectrometer. The device has a first gas pressure region and a second gas pressure region lower than the first gas pressure region. The device includes: a heating desorption device, carrying a sample and heating the sample, an analyte in the sample is desorbed from the sample under a heating action and then enters the first gas pressure region; a vacuum interface component, connected with the first gas pressure region and the second gas pressure region, and causing the analyte to enter the second gas pressure region from the first gas pressure region under the drive of a gas flow; and a soft ionization source, converting gas molecules in the second gas pressure region into activated gas molecules, the analyte entering the second gas pressure region realizes soft ionization after interacting with the activated gas molecules.
