Degassing device of ion chromatograph

The invention relates to the technical field of ion chromatographs, in particular to an ion chromatograph degassing device which comprises a degassing box, a degassing pipeline, a negative pressure pipe and an absorption pipe. The negative pressure pipe is arranged in the gas pipe, one end of the gas pipe is connected with the absorption pipe, the carbon dioxide adsorbent in the absorption pipe adsorbs carbon dioxide gas in the air, and then the carbon dioxide gas is sucked into the degassing box through the negative pressure pipe, so that the concentration of carbon dioxide in the degassing box is lower than that in the degassing pipe, and meanwhile, the degassing box is in a low-pressure state; under the action of pressure difference and concentration difference, gas in leacheate and a sample can be effectively removed when the leacheate and the sample flow through the degassing pipe, particularly, the removal efficiency of carbon dioxide gas is higher, and the removal effect is better. By arranging the neg
