Data Collection Stops Early - Instrument Failures - Empower 2 busSAT/IN
Has anyone experienced issues with data collection stopping early in Empower 2? We've observed several chromtagraphy runs stop collecting a minute or so early. Typically there are no signs of instrument failure, although we observed one run stop 1 minute early for one injection, two minutes early for the subsequent injection and fail altogether in the next injection. So far there have been no observed issues with the related instruments and their programmed run times. This group is using busSAT/IN's only, no software/instrument control. It appears that data collection may be starting later than expected based on the elution profile on the chromatograms. We've also experienced "instrument failures" of busSAT/INs with no assignable cause. They are displayed as "Instrument Failure: Unspecified Instrument", Instrument Failure" or Instrument Failure SAT/[email protected] in the Message Center. These runs frequently run to completion on the instrument, but data collection stops altogether in Empower 2. Waters has not been able to identify any causes of these issues so far. Thanks for any knowledge that you can pass on.
