1, the concentration of oxygen is not the same. Industrial oxygen contains more impurities, and the oxygen concentration of more than 99% is qualified. Medical oxygen has high purity, oxygen content of not less than 99.5%, colorless, tasteless, less harmful impurities.
2, the scope of use is different. Medical oxygen is for clinical medical use of oxygen, commonly known as dry oxygen, mainly for the prevention and treatment of patients with hypoxia, industrial oxygen, literal interpretation is used for industrial production and product processing of oxygen.
3, moisture control is different. Medical oxygen, the requirements of the water content is very low, because the water will make the iron oxidation if inhaled into the human body will produce great harm, industrial oxygen is industrial use, there is no strict requirements for moisture. p>It is reported that in China, medical oxygen manufacturers must invest heavily in GMP production transformation, through the certification of the product can be marketed, industrial oxygen is not this requirement.
Additionally, medical oxygen must be tested for impurities, once the impurities exceed the standard, can not be shipped, while the industrial oxygen does not have the requirements in this regard, so the price of medical oxygen on the market is often two or three times the price of industrial oxygen.
It is reported that there are two kinds of oxygen used in medical institutions in China, one is as a drug to manage the medical oxygen, the other is the hospital's own oxygen, through the installation of a set of molecular sieve equipment will be processed in the hospital air to become oxygen.
The reason why hospitals are so keen to make their own oxygen, and the interests are inseparable, the general hospitals need two sets of equipment, up to millions of dollars, selling oxygen but big money.
