How to enable post-run shutdown in OpenLAB CDS 2.2?

We've recently switched one of our HPLC systems from Chemstation to Openlab v2.2. I can't find the option to shut down/go to standby once all queued runs are completed, meaning the pump continues running until the low solvent trigger point is hit (which is a big waste of solvent!). I can't find any mention of it in the Help & Learning resources. I know on Chemstation the shutdown procedures were specified on the Sequence Parameters dialogue. What's the alternative for OpenLab v2.2?

Thanks in advance!

  • You're right, it only shuts down the detector.  In your answer above, you mention creating a shutdown method, which is what you would need to do, in addition to changing the Instrument Options, otherwise the detector lamp will remain on.

     

    What I have done in OpenLab 2.2 is to create a method called shutdown, which has no flow from the pump and no temperature control on the column thermostat.  I then either add this to the end of the sample queue as a single sample (Instrument Blank as the Injection Source) or create a separate sequence with one injection using the same method to do the same thing.  I normally end up doing this as a sequence, and include a column wash or column storage method as well.  Keeping the wash/store/off methods in a separate sequence means that, when it comes to data processing, I don't have odd results with no peaks and different run times to exclude from reports!
