Acetylene (C2H2) Calibration Gas

11998

Acetylene calibration gas is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colourless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odourless, but commercial grades usually have a marked odour due to impurities. Acetylene is not especially toxic, but when generated from calcium carbide, it can contain toxic impurities such as phosphine and arsine traces, giving it a distinct garlic-like smell. It is also highly flammable, as are most light hydrocarbons, hence its use in welding. 34L 58L 110L Cert. tol. Prod. tol.

Ammonia (NH3) Calibration Gas

12005

Ammonia calibration gas is a compound of nitrogen and hydrogen with the formula NH 3 . Ammonia is a colourless gas with a characteristic pungent smell, a stable binary hydride, and the simplest pnictogen hydride. This type of gas, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. Various forms of ammonia calibration gas are available. 34L 58L 110L Cert. tol. Prod. tol.

Argon (Ar) Calibration Gas

12050

Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth™s atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth™s crust, comprising 0.00015% of the crust. 34L 58L 110L Cert. tol. Prod. tol.
