High moisture content in GCMS

During tuning my GCMS has high moisture content, but it is free of oxygen and nitrogen. The moisture filter is also ok, I also replaced the helium gas source, but the problem still exists.

Please  suggest me any probable causes?

  • Hi

    Which model you are using?

    Can you share tuning report.

    Any recent maintenance performed, if, yes, then what consumables replaced.

    How is inlet of gc, is it okay

    How is split vent filter?

    First make sure GC side, everything is okay then can go to see MS..

    But share tuning report to understand better...

  • Hi,

    It is 7000D model. There is no any maintenance performed. It is a new system just after installation. So, the split vent filter is supposed to be clean..

    I attached the tune report for your reference.

  • Hi

    Do baking of MS then check.

    I think after baking, moisture will go down from 125%.

    If not, then we have to do maintainence of GC first then check and at last we have to focus on MS.

    As per my experience, baking of ms should solve this moisture problem...
