How to adjust a gas chromatograph to monitor certain gases?
Thread Content
For example, a gas chromatograph has already been specified under the original conditions; now new types of gases are to be added. How should the gas chromatograph be modified to meet these new measurement requirements? For another example, there used to be a flow path that measured oxygen plus argon; now we want to know the oxygen level separately. Can this be modified?
Didn’t your test show the presence of organic matter? What detector? It is estimated that both the root post and the pressure gauge need to be checked to determine if they need to be replaced
The chromatographic detection is different; the chromatography columns are different, so they cannot be used.
