Hydrogen Sulfide

Hydrogen Sulfide, H2S Specialty Gas Product Description Hydrogen sulfide  is an inorganic compound that is a flammable acid gas at standard conditions and has a rotten egg smell in low concentrations. Hydrogen sulfide is a colorless, highly toxic, flammable gas with a stench characteristic of rotten eggs. It is usually caused by bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers where anaerobic digestion can take place. It is also present in volcanic gases, "natural gas" and some well waters. Hydrogen sulfide has many names, some of which are ancient. Crude oil contains small amounts of hydrogen sulfide, but natural gas can contain up to 90 percent hydrogen sulfide. About 10% of total global H2S emissions are caused by human activities.

Boron Trifluoride, BF3 Specialty Gas

图片
Boron Trifluoride, BF3 Specialty Gas Boron trifluoride (BF3)  is a colorless gas with   a strong smell at room temperature. It does   not bum or support combustion. Itis 1.3   times heavier than air and produces white   smoke when mixed with wet air, with a punity   higher than 99.6%. Boron trifluoride can   corrode glass at room temperature, while wet   boron trifluoride is very corrosive. BF3 is   used as a catalyst in organic synthesis, as a   raw material for the synthesis of organic   borides, and also used in nuclear technology   and optical fiber.
