As an important chemical raw materia...Read more -
High Purity Methane
Definition and Purity Standards of High-Purity Methane High-purity methane refers to methane gas with a relatively high purity. Generally, methane with a purity of 99.99% or higher can be considered high-purity methane. In some more stringent applications, such as the electronics industry, purity...Read more -
Conventional Applications of Ethylene Oxide (EO) Sterilization
Ethylene oxide EO Gas is a highly effective sterilant widely used in medical devices, pharmaceuticals, and other applications. Its unique chemical properties enable it to penetrate complex structures and kill microorganisms, including bacteria, viruses, fungi, and their spores, without damaging m...Read more -

Rare gases: Multidimensional value from industrial applications to technological frontiers
Rare gases (also known as inert gases), including helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), are widely used in many fields due to their highly stable chemical properties, colorless and odorless, and difficult to react. The following is a classification of their core uses: Shie...Read more -
Electronic gas mixture
Specialty gases differ from general industrial gases in that they have specialized uses and are applied in specific fields. They have specific requirements for purity, impurity content, composition, and physical and chemical properties. Compared to industrial gases, specialty gases are more diver...Read more -
Gas Cylinder Valve Safety: How much do you know?
With the widespread use of industrial gas, specialty gas, and medical gas, gas cylinders, as core equipment for their storage and transportation, are crucial for their safety. Cylinder valves, the control center of gas cylinders, are the first line of defense for ensuring safe use....Read more -
The “miracle effect” of ethyl chloride
When we watch football games, we often see this scene: after an athlete falls to the ground due to a collision or sprained ankle, the team doctor will immediately rush over with a spray in hand, spray the injured area a few times, and the athlete will soon be back on the field and continue to par...Read more -
Diffusion and distribution of sulfuryl fluoride in wheat, rice and soybean grain piles
Grain piles often have gaps, and different grains have different porosities, which leads to certain differences in the resistance of different grain layers per unit. The flow and distribution of gas in the grain pile are affected, resulting in differences. Research on the diffusion and distributi...Read more -
Relationship between sulfuryl fluoride gas concentration and warehouse air tightness
Most fumigants can achieve the same insecticidal effect by maintaining a short time at a high concentration or a long time at a low concentration. The two major factors for determining the insecticidal effect are the effective concentration and the effective concentration maintenance time. The in...Read more -
New environmentally friendly gas Perfluoroisobutyronitrile C4F7N may replace sulfur hexafluoride SF6
At present, most GIL insulation media use SF6 gas, but SF6 gas has a strong greenhouse effect (global warming coefficient GWP is 23800), has a great impact on the environment, and is listed as a restricted greenhouse gas internationally. In recent years, domestic and foreign hotspots have focused...Read more -
