Carbon Dioxide (CO2) Calibration Gas
12068
Carbon dioxide (chemical formula CO2 ) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth™s atmosphere as a trace gas. The current concentration is about 0.04% (410 ppm) by volume, having risen from pre-industrial levels of 280 ppm. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide is odorless at normally encountered concentrations, but at high concentrations, it has a sharp and acidic odor. 34L 58L 110L Cert. tol. Prod. tol.

Ethanol (C2H6O) Calibration Gas
12074
Ethanol (also called ethyl alcohol , grain alcohol , drinking alcohol , or simply alcohol ) is a chemical compound, a simple alcohol with the chemical formula C 2 H 6 O . Its formula can be also written as CH 3 ˆ’ CH 2 ˆ’ OH or C 2 H 5 OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH . Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is a psychoactive substance and is the principal active ingredient found in alcoholic drinks. Ethanol is naturally produced by the fermentation of sugars by yeasts or via petrochemical processes, and is commonly consumed as a popular recreational drug. It also has medical applications as an antiseptic and disinfectant. The compound is widely used as a chemical solvent, either for scientific chemical testing or in synthesis of other organic compounds, and is a vital substance used across many different kinds of manufacturing industries. Ethanol is also used as an alternative fuel source. 34L 58L 110L Cert. tol. Prod. tol.

Helium (He) Calibration Gas
12081
Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. Helium is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). Most helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium are being created by nuclear fusion of hydrogen in stars. 34L 58L 110L Cert. tol. Prod. tol.

Ethylene Oxide (ETO) (C2H4O) Calibration Gas
12084
Ethylene oxide , called oxirane by IUPAC, is an organic compound with the formula C 2 H 4 O . It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a number of addition reactions that result in ring-opening. Ethylene oxide is isomeric with acetaldehyde and with vinyl alcohol. Ethylene oxide is industrially produced by oxidation of ethylene in the presence of silver catalyst. 34L 58L 110L Cert. tol. Prod. tol.
