GCMS tuning stopped 5975C

Hello All,

I'm seeing an issue that I haven't come across before - have just changed the column and pumped back down yesterday. Came to do an air and water check this morning and i get the below: 

Tune action stopped:-222{SP00}:MSC:RDY ON Parameter ento value 64.256 out of range [0.000, 64.000]

I didn't do anything with the source yesterday, just changed the column....

Thanks in advance!

  • Or if you no idea then better call to your local agilent support to log service call...

  • I tried to add the tune reports as pdfs but couldn't upload.... Thanks both ISH and paulsalverda for your replies, we got the system second hand so I don't have a 'local' agilent engineer I can call on! I have no experience of removing and cleaning the source of this system but it is looking likely I'll need to. 

    The curious thing is that the only difference between the good tune a week prior and the bad tune last week is that I had to vent and clear some debris out of the analyser chamber...I didn't actually touch the source or run any samples so its strange that suddenly the tune has an issue :(
