Furthermore, a vacuum pump (not shown) is connected to the exhaust port 9 of the container 6 to reduce the pressure inside the container 6. The porous tube 7 is formed into a tube shape using a membrane material, such as a membrane material made of fluororesin or silicone resin, having a large number of fine pores that allow only gas to pass through and prevent liquid from permeating. Therefore, if this second mixing device 4 is used in combination, more reliable mixing can be performed, and at the same time, dissolved gas can be degassed from the liquid, making it unnecessary to incorporate a degassing device into the Liquid Chroma 1-Graph. You will be able to get away with it.
