| titleOfInvention | A matrix-assisted laser desorption ionization source |
| abstract | The utility model relates to the technical field of mass spectrometry analysis, in particular to a matrix-assisted laser analysis ionization ion source, comprising a desorption laser, a laser focusing system, an ion pulling electrode, a sample target, a translation stage and a CCD camera, wherein the sample target is arranged on the translation stage , there is a mass spectrometer above the sample target, the desorption laser and the CCD camera are located on both sides of the mass spectrometer, and the laser focusing system is located on the light-emitting side of the desorption laser, which is used to focus the laser and inject it into the surface of the sample target; the CCD camera is used for The morphology of the action point of the laser and the sample target is taken. An ion traction electrode is arranged between the mass spectrometer and the sample target. A ground electrode is arranged at the ion inlet of the mass spectrometer. The matrix-assisted laser desorption ionization ion source provided by the utility model can effectively shield the external ion traction electric field, and at the same time ensure the transmittance of the ions, which is beneficial to the detection of the mass spectrometer, and is suitable for further popularization and application. |
