Sample introduction system and sample introduction method for electron cyclotron resonance mass spectrometer

The invention provides a sample introduction system and a sample introduction method for an electron cyclotron resonance mass spectrometer. The sampling system comprises an ultrasonic atomizer, a membrane desolventizing device and a diaphragm pump, the membrane desolventizing device comprises a semi-permeable membrane inner tube and a glass outer tube, the glass outer tube is coaxially arranged outside the semi-permeable membrane inner tube in a surrounding mode, the inlet end and the outlet end of the semi-permeable membrane inner tube are communicated with the ultrasonic atomizer and the diaphragm pump respectively, and the glass outer tube is communicated with a vacuum system. And the outlet end of the diaphragm pump is connected with the electron cyclotron resonance mass spectrometer. According to the sample introduction system and the sample introduction method, the sample introduction rate is greatly improved, the bad problems of blockage and the like caused by direct liquid sample introduction are solv
