The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrating the present invention and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

In a specific embodiment, a porous glass plate absorption tube is provided, which is generally made of glass material, and specifically comprises a thin tube 1 and a thick tube 3 which are vertically arranged in parallel, wherein the thin tube 1 and the thick tube 3 are opposite to each other in terms of "thin" and "thick". The bottom ends of the two are communicated through a U-shaped pipe 2. The top of the thick tube 3 is communicated with a spherical tube 4 with the diameter larger than that of the thick tube 3, the inner side of the bottom of the thick tube 3 is provided with a porous glass plate 3.1, when gas passes through the porous glass plate 3.1, the gas can be dispersed in the detection gas flow to be fully contacted with the detection liquid so as to improve the reaction efficiency, wherein, the spherical tube 4 with the diameter of the thick tube 3 mainly acts on providing a buffer space for reaction, and the phenomenon that the reaction is too strong or too many bubbles are generated to overflow the outside of the tube is avoided. In addition, the gas pressure can be avoided pushing the liquid out of the tube. The structure form and the use mode of the specific tube body are the same as those of the existing porous glass plate absorption tube. And thus will not be described in detail.

In order to further solve the problem of difficult liquid injection of the existing porous glass plate absorption tube, the structure of the existing porous glass plate absorption tube is improved, and the top end structures of the thin tube 1 and the thick tube 3 are mainly improved. The method comprises the following specific steps:

the top end of the thin tube 1 is provided with a first top tube 1.1 which is bent towards the outer side of the thin tube and is communicated with the thin tube 1, and a second top tube 1.2 which is coaxially arranged with the thin tube 1 and is communicated with the thin tube 1 (see figures 1-4);

similarly, a transition pipe 5 is communicated with the top of the spherical pipe 4, a third jacking pipe 5.1 which is bent towards the outer side of the transition pipe 5 and communicated with the transition pipe 5 is arranged at the top end of the transition pipe 5, and a fourth jacking pipe 5.2 which is coaxially arranged with the transition pipe 5 and communicated with the transition pipe. (see FIGS. 1-4)

As the preferred embodiment of the embodiment, the included angle between the axis of the first top pipe 1.1 and the axis of the second top pipe 1.2 and the included angle between the third top pipe 5.1 and the fourth top pipe 5.2 are both 65-80 degrees, so that the ports of the first top pipe 1.1 and the third top pipe 5.1 are ensured to be arranged obliquely upwards, and further, the phenomenon that the reaction is too strong or too many bubbles are generated to overflow the outside of the pipe can be effectively avoided, and the outflow of liquid during liquid discharging can also be avoided.

In addition, two upper plugs 6 are arranged at the top of the absorption tube and can be hermetically buckled at the ends of the second top tube 1.2 and the fourth top tube 5.2 or at the ends of the first top tube 1.1 and the third top tube 5.1;

In addition, in order to further facilitate the plugging and unplugging of the upper plug 6, the connecting rope 6.1 is an elastic connecting rope, so that the upper plug 6 can be buckled on any top pipe while the connecting rope 6.1 is not loosened, and the use convenience is improved.

In the specific liquid injection operation, in order to solve the problems that liquid is difficult to inject into the tube due to the fact that a pipeline at an inlet for injecting reaction liquid is bent, the liquid overflows to cause inaccuracy of sampling liquid, and further deviation of detection results is caused, in the embodiment, a second top tube 1.2 and a fourth top tube 5.2 which are vertically arranged are arranged above the bent first top tube 1.1 and the bent third top tube 5.1. When tapping, the upper plug 6 is first opened and tapping is performed by a pipette or a syringe. Because the body does not bend the separation and directly can deliver to spherical pipe 4 with pipette or syringe head flowing back end in to pipette or syringe head flowing back end is usually thinner, can leave the space with the body is inside, and at this moment, first push pipe 1.1 or third push pipe 5.1 can assist the discharge of intraductal gas, reduce tapping resistance effective control tapping precision, and then avoid the tapping overflow, and then improve the precision and the tapping efficiency of tapping at a certain degree. (see FIG. 5)

After liquid discharge, the upper plug 6 is buckled on the second jacking pipe 1.2 and the fourth jacking pipe 5.2, so that gas component detection and analysis of the porous glass plate absorption pipe are realized. (see FIG. 5)

In the specific detection process, firstly, a negative pressure device is connected with the 5.1 end of the third top pipe, the flow speed and the flow of negative pressure airflow are adjusted, so that gas to be detected enters the thin pipe 1 from the 1.1 port of the first top pipe and reaches the porous glass plate 3.1 to generate a large amount of micro bubbles, the gas and the liquid are fully fused or substances to be detected in the gas and the liquid are chemically generated, and after the detection time is reached, the liquid after detection is taken out for further assay. There are two types of removal methods, the first being to pour the liquid directly from the third top pipe 5.1, and the second being to blow air into the third top pipe 5.1 to discharge the liquid from the first top pipe 1.1. However, neither of these approaches is able to completely drain the liquid from the bottom U-shaped structure, and the first type of drainage is inefficient.

Therefore, on the basis of the above embodiment, in order to facilitate the liquid discharge and collection after detection and to facilitate the cleaning of the tube body, the bottom of the tube body is improved, specifically as follows:

During the specific liquid drainage operation, liquid drainage is also carried out by adopting the formation of air blowing in the pipe, the upper plug 6 is plugged on the first top pipe 1.1 and the third top pipe 5.1 or the second top pipe 1.2 and the fourth top pipe 5.2, air blowing is carried out by utilizing two unblocked ports, and liquid is quickly discharged from the liquid drainage port 2.1 through pressure;

on the other hand, when clearing up the body, preferably with plug 6 stifled on first push pipe 1.1 and third push pipe 5.1, adopt second push pipe 1.2 or fourth push pipe 5.2 arbitrary one end as the end of intaking, the other end then regards as the drainage end, accomplishes the clearance repeatedly, wherein, second push pipe 1.2 and the vertical setting of fourth push pipe 5.2 can reduce the resistance to rivers. In addition, the second top pipe 1.2 and the fourth top pipe 5.2 are vertically arranged, so that resistance to water flow can be reduced, open ends of the second top pipe 1.2 and the fourth top pipe 5.2 face downwards, so that water in the pipes can be quickly thrown out, and residues of cleaning water in the pipes are reduced. The cleanliness of the tube body is improved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
