Sumairui gas have two types of nitrogen purifier to get high purity 99.999% ：
1. Hydrogeneration purifier（ OSP-H ）
Add hydrogen to the crude nitrogen (99-99.9% purity),react with oxygen in ordinary
nitrogen gas under the action of catalyst, Producing water ,And then through the molecular
sieves adsorption to obtain the high purity nitrogen.
