Abstract: The utility model discloses an electrospray ionization device directly analyzing solid samples. The device comprises an injector and a metal needle on the front end of the injector, and an injection pump and a pipettor tip connected with the rear end of the injector. High voltage electricity is loaded after the metal needle is inserted into the pipettor tip. The device uses the injection pump to drive the injector to continuously guide solvent into the pipettor tip, the solvent flows through the solid sample in the pipettor tip and extracts the sample. High-voltage electricity is loaded on the metal needle, and is conducted to the tip outlet of the pipettor tip through the solvent, so as to induce output solution to form electrospray ionization. Ions ionized by electrospray are directly led into a mass spectrometer to measure, and a mass spectrum is obtained. The device is simple, economical, durable, and can rapidly and directly perform electrospray ionization mass spectrometry on solid samples. The device can be assembled in most mass spectrometry laboratories and can be applied in electrospray ionization mass spectrometers in various models.
