What instrument is used to measure pure hydrogen?
Thread Content
The instrument my company uses to measure pure hydrogen is the Guidjin gas chromatograph JC-2104, and I always feel that the measurements of the samples are inaccurate I’m not very familiar with laboratory tests. What instruments do people use for pure hydrogen testing? Thank you
If even such precise chromatography is considered inaccurate, then aging the column and creating a calibration curve should not result in extreme values, right?
For testing pure hydrogen, any chromatography manufacturer’s equipment can be used; the key is the method: hydrogen is used as the carrier gas for pure hydrogen, and impurities such as nitrogen, oxygen, and COx are detected, after which the purity of hydrogen is calculated using the subtraction method.
