Sulphur Hexafluoride - SEMA Gases
Sulphur Hexafluoride (SF6)
Sulfur hexafluoride (SF6) is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents. It is generally transported as a liquefied compressed gas. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L).
SEMA Gases is a manufacturer of span gases in disposable cylinder cans from the Netherlands, established from the want to create a label which is applicable for all brands of gas detection equipment. The products of SEMA Gases are used for calibration of portable gas detection instruments and calibration of fixed gas detection systems. SEMA Gases produces single gases (flammable gases, oxygen, toxic gases) and gas mixtures (2, 3, 4 or 5 gas mixtures) in various cylinder size up to 110 ltr.
