This utility model relates to the field of toxic gas sampling technology, and is an online closed sampling device for toxic gases. It includes a transparent box, a box support, an air inlet assembly, and protective gloves. The box support is located at the bottom of the transparent box. The air inlet assembly includes a first straight pipe section, a second straight pipe section, an air inlet hose, and a gas connection hose. An air inlet hole is provided on the top wall of the transparent box. The first straight pipe section extends from the outside of the transparent box through the air inlet hole into the interior of the transparent box. A hand valve is fixedly installed on the second straight pipe section. The front wall of the transparent box is designed with symmetrical double doors, including a left door and a right door. The left and right doors each have symmetrical left and right hand holes, and protective gloves are fixedly installed in both the left and right hand holes to reach into the transparent box. This utility model has a reasonable and compact structure, is easy to use, and improves both the safety and efficiency of online toxic gas sampling.

The present application relates to pet trace element instant beverage technical field, specifically to double-bin isolation instant pet trace element beverage and its preparation method, the pet trace element instant beverage is composed of double-bin packaging, high-activity pet trace element instant powder and buffer pure base fluid; The double-bin packaging includes upper powder bin and lower liquid bin, the easy-to-tear aluminum foil diaphragm is arranged between the upper powder bin and the lower liquid bin. The present application realizes the long-term stable storage of trace elements through the synergistic design of double-bin isolation structure, special instant formula and convenient use method, without refrigeration, the shelf life of 18 months can be achieved, the activity retention rate is greater than or equal to 95%; Using special instant emulsifying system, 3-5 seconds of instantaneous instant can be realized under the condition of low shear force hand shaking, there is no stratification, no caking, no wall hanging, and the absorption efficiency is improved by more than 60% compared with existing products.
