Ion chromatograph capable of improving measurement accuracy

The utility model discloses an ion chromatograph capable of improving measurement accuracy, and relates to the technical field of chromatographs, the ion chromatograph comprises a chromatograph body, the top of the chromatograph body is fixedly connected with a level bubble, and the bottom of the chromatograph body is provided with a supporting plate. Through cooperative arrangement of the supporting plate, the threaded pipes, the threaded rods, the level bubble, the base and other structures, during use, whether the chromatographic instrument body is horizontal or not is judged through the level bubble, and when the chromatographic instrument body is in an inclined state, a user rotates different threaded pipes and moves the threaded rods screwed to the two ends of the threaded pipes in the same direction or in the opposite direction, so that the chromatographic instrument body is inclined. The heights of the threaded rods screwed with the tops of the threaded pipes are adjusted, the chromatographic instrume
