When the gas passes through the porous glass plate 3.1, it can disperse the gas flow to be detected The liquid is fully contacted to improve the reaction efficiency, wherein the main function of the spherical tube 4 with the diameter of the thick tube 3 is to provide a buffer space for the reaction, so as to prevent the reaction from being too strong or excessive bubbles from overflowing the tube. In addition, it is possible to prevent the gas pressure from pushing the liquid out of the tube. The specific structure and use of the above-mentioned tube body are the same as those of the existing porous glass plate absorption tube. So no more details.

In order to further solve the problem of difficulty in injecting liquid into the existing porous glass plate absorption tube, the structure of the existing porous glass plate absorption tube is improved, mainly the top structures of the thin tube 1 and the thick tube 3 are improved. details as follows:

Similarly, a transition pipe 5 is provided in communication with the top of the spherical pipe 4, and a third top pipe 5.1 bent to its outside and communicated with the transition pipe 5 is provided at the top of the transition pipe 5, and is coaxially arranged with the transition pipe 5 and It communicates with the fourth jacking pipe 5.2. (See Figure 1-Figure 4)

As a preferred embodiment of this embodiment, the included angle between the axis of the first jacking pipe 1.1 and the axis of the second jacking pipe 1.2 and the angle between the third jacking pipe 5.1 and the fourth jacking pipe 5.2 are both 65°-80° °, so as to ensure that the ports of the first jacking pipe 1.1 and the third jacking pipe 5.1 are set obliquely upwards, thereby effectively preventing the reaction from being too strong or excessive bubbles from overflowing the pipes, and also avoiding the outflow of liquid when discharging.
