Ethylene oxide sterilization
The common ethylene oxide sterilization process uses a vacuum process, generally using 100% pure ethylene oxide or a mixed gas containing 40% to 90% ethylene oxide (for example: mixed with carbon dioxide or nitrogen). Properties of Ethylene Oxide Gas Ethylene oxide sterilization is a relatively r...Read more -
Properties and characteristics of electronic grade hydrogen chloride and its application in semiconductors
Hydrogen chloride is a colorless gas with a pungent odor. Its aqueous solution is called hydrochloric acid, also known as hydrochloric acid. Hydrogen chloride is very soluble in water. At 0°C, 1 volume of water can dissolve about 500 volumes of hydrogen chloride. It has the following properties a...Read more -

Applications of Deuterium
Deuterium is one of the isotopes of hydrogen, and its nucleus consists of one proton and one neutron. The earliest deuterium production mainly relied on natural water sources in nature, and heavy water (D2O) was obtained through fractionation and electrolysis, and then deuterium gas was extracted...Read more -
Commonly used mixed gases in semiconductor manufacturing
Epitaxial (growth) Mixed Gas In the semiconductor industry, the gas used to grow one or more layers of material by chemical vapor deposition on a carefully selected substrate is called epitaxial gas. Commonly used silicon epitaxial gases include dichlorosilane, silicon tetrachloride and silane. M...Read more -
How to choose mixed gas when welding?
Welding mixed shielding gas is designed to improve the quality of welds. The gases required for the mixed gas are also the common welding shielding gases such as oxygen, carbon dioxide, argon, etc. Using mixed gas instead of single gas for welding protection has a good effect of significantly ref...Read more -
Environmental testing requirements for standard gases / calibration gas
In environmental testing, standard gas is the key to ensure measurement accuracy and reliability. The following are some of the main requirements for standard gas: Gas purity High purity: The purity of the standard gas should be higher than 99.9%, or even close to 100%, to avoid interference of i...Read more -
