Heptane (C7H16) Calibration Gas
12087
n -Heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2 ) 5 CH 3 or C 7 H 16 , and is one of the main components of gasoline (petrol). When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane). Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline (petrol) dispensed globally. 34L 58L 110L Cert. tol.

Hexane (C6H14) Calibration Gas
12093
Hexane is an alkane of six carbon atoms, with the chemical formula C 6 H 14 . The term may refer to any of the five structural isomers with that formula, or to a mixture of them. Hexanes are significant constituents of gasoline. They are all colorless liquids, odorless when pure, with boiling points between 50 and 70 °C (122 and 158 °F). They are widely used as cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvents. 34L 58L 110L Cert. tol. Prod. tol.

Hydrogen Sulphide (H2S) Calibration Gas
12107
Hydrogen sulfide is the chemical compound with the formula H 2 S . It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H 2 S also occurs in volcanic gases, natural gas, and in some sources of well water. The human body produces small amounts of H 2 S and uses it as a signaling molecule. 34L 58L 110L Cert. tol.

Methane (CH4) Calibration Gas
12113
Methane is a chemical compound with the chemical formula CH 4 . It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, although capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor, and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth™s atmospheric methane concentration has increased by about 150% since 1750. 34L 58L 110L Cert. tol. Prod. tol.

Nitrogen (N2) Calibration Gas
12119
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bind to form dinitrogen , a colourless and odorless diatomic gas with the formula N 2 . Dinitrogen forms about 78% of Earth™s atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins). The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates, and cyanides, contain nitrogen. 34L 58L 110L Cert. tol. Prod. tol.
