What are the analysis methods for hydrogen purity? To detect at the 5N level
Thread Content
The company is now planning to install a hydrogen purification unit, with the requirement that the purity of the hydrogen reach 5N. What are the testing methods and instruments available for this?
The purity of hydrogen is high; generally, impurities are analyzed to identify what they are, and ultimately 100% is subtracted based on those findings

First, it is necessary to know the types and amounts of impurities present in the mixture: depending on the process used to produce hydrogen, determine which types of impurities might be present in that process, and then take samples of these impurities to send to a testing laboratory for analysis. Then, for these types of impurities, different devices are used to remove them.
It can detect impurities at the PPB level and above; all types of impurities can be detected using a single machine, without the need for additional modules.
