Silane (SiH4) Calibration Gas
12179
Silane is an inorganic compound with chemical formula, SiH 4 , making it a group 14 hydride. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon. œSilanes refers to many compounds with four substituents on silicon, including an organosilicon compound. Examples include trichlorosilane (SiHCl 3 ), tetramethylsilane (Si(CH 3 ) 4 ), and tetraethoxysilane (Si(OC 2 H 5 ) 4 ). Silane Calibration Gases 34L 58L 110L Cert. tol. Prod. tol.

Sulphur Hexafluoride (SF6) Calibration Gas
12187
Sulfur hexafluoride (SF 6 ) is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 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). Sulphur Hexafluoride Calibration Gases 34L 58L 110L Cert. tol. Prod. tol.

Toluene (C7H8) Calibration Gas
12190
Toluene , also known as toluol , is an aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a CH 3 group attached to a phenyl group. As such, its IUPAC systematic name is methylbenzene . Toluene is predominantly used as an industrial feedstock and a solvent. Toluene Calibration Gases 34L 58L 110L Cert. tol. Prod. tol.

Vinyl Chloride (VCM) (C2H3Cl)
12193
Vinyl chloride is an organochloride with the formula H 2 C=CHCl that is also called vinyl chloride monomer ( VCM ) or chloroethene . This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). About 13 billion kilograms are produced annually. VCM is among the top twenty largest petrochemicals (petroleum-derived chemicals) in world production. Vinyl chloride is a gas with a sweet odor. It is highly toxic, flammable, and carcinogenic. It can be formed in the environment when soil organisms break down chlorinated solvents. Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills. In the past VCM was used as a refrigerant. Vinyl Chloride Calibration Gases 34L 58L 110L Cert. tol. Prod. tol.

Carbon Monoxide (CO) Calibration Gas
12196
Carbon monoxide ( CO ) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air. It is toxic to animals that use hemoglobin as an oxygen carrier (both Invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone. Carbon Monoxide Calibration Gases 34L 58L 110L Cert. tol. Prod. tol.

Calibration Gas / Test Gas
1253
Calibration gas is a reference gas or a mixture of gases which are usually compressed. The composure of calibration gas exists of one initial gas and is enhanced by one or more component(s). Calibration gas is used to calibrate gas analysers or gas detectors. All SEMA calibration gas cylinders (Flammable, Toxics, Oxygen, and mix gas) are traceable according to national (Dutch) as well as international criteria. Calibration gases can be divided into two categories; zero calibration and span calibration. Zero calibration gas is a gas which is free from flammable gases. Zero calibration gases are performed when gas detection or gas analysers get calibrated with none of the analyte gas structures to which the analyser or detector will respond. For example, a zero calibration of an oxygen-, or carbon dioxide analyser can be performed with pure nitrogen. Because nitrogen does not hold either oxygen or carbon dioxide, a zero point can be confirmed this way. A span gas calibration is a more advanced type of calibration gas by which there is a precisely composed concentration of detectable gas exposed towards the gas detector or gas analyser. SEMA Gases delivers multiple types of calibration gases suitable for the shipping industry, offshore industry, chemical industry, laboratories, and universities.
