Nitrogen Dioxide (NO2)
Nitrogen dioxide is the chemical compound with the formula NO2. It is one of several nitrogen oxides. NO2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year which is used primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant. Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry.
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.
