Medical gases are regulated by the United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP) that sets standards for all medical gases including those that address quality, strength, purity, packaging, labeling, and identification. HORIBA contributes in this field by providing a wide range of analysis and measurement solutions with high accuracy.
The medical gases used in a hospital are life-supporting element that gives direct influence on maintaining the life of patients. Therefore, at the sections where the medical gases are used, the medical gas must be clean and highly pure. For the European Pharmacopoeia, the analytical methods and the concentration are strictly addressed in the guideline.
Medical oxygen is usually produced by the air separation plant. Air separation plant separates atmospheric air into its primary components oxygen (O2), nitrogen (N2), and argon (Ar) by distillation at cryogenic temperatures. Separation of air is performed in the distillation unit using the difference in the boiling points of each constituent gas. Produced in ASU medical gas is distributed to its users in gas cylinder truck. Quality assurance process is conducted before distribution to ensure, if the oxygen product meets the required standard and its expectations.
