7890B GC with 7200 QTOF Masscal Failing Intermittently

Hi all,

I am having a recurring issue throughtout my sequences. When I check the sequence log after a run, where I place a masscal between each sample, I see in the sequence log the following error:

  5) MassCal: ' '
     Starting QTOF MassCal: Mon Nov 01 22:59:47 2021
    QTOF MassCal reports Fail Mon Nov 01 23:01:01 2021

There is no pattern to it failing, sometimes it passes, sometimes it fails. I'm not sure on what criteria the masscal is failing, so as to investigate further.

Any help is much appreciated, thanks in advance
