Nitric Oxide Supplier to St. Louis Cee Kay Supply, Inc. is happy to make PurityPlus® Nitric Oxide (NO), a colorless, nonflammable but toxic oxidizing gas, available for professional use in St. Louis. Nitric Oxide is produced as a pollutant via the combustion of fossil fuels in the presence of excess oxygen. It is also produced by the direct reaction of atmospheric nitrogen to oxygen during electrical storms. For the commercial market, all high-purity Nitric Oxide is obtained from the oxidation of ammonia by means of a platinum catalyst and heat. Small measures of NO can be produced in the laboratory by taking diluted nitric acid and reducing it with copper. The majority of the Nitric Oxide made is used as an intermediate in the formulation of concentrated nitric acid. High-purity Nitric Oxide is used in calibration standards for environmental emission monitoring, industrial hygiene monitors, and trace impurity analyzers. NO is also introduced into gas mixtures to treat pulmonary arterial hypertension and is finding increasing use as well in many pharmacological research applications employing vasodilation as a means of pain reduction.
