Warning: calibrated compound not found (GC-7890b)

Hi Milad,

Your problem is very strange.  What version of OpenLab are you using?  Is this the only method this happens with?

Could you attach the method and data files?  It would be very helpful if I could take a close look at both.

Dear Tim [hebgent],

Thank you so much for your reply.

I have attached the method and data files. Please find them. In this file, 7890-0505 HS Samples_unsaved changes.M is the method, high1.D is standard and 1D.0D is my sample.

Previously we didn't see this problem.

When u check the scale of the succesfull run its quiete different from the one u don't see any signal at all.

The second one is either a blank, or the compound didn't reach the detector.

I once had the problem that I selected the wrong detector at the end.

Dear Abbey,

Sorry for the late response,

Thank you so much for your explanation, it is like a guideline.

I checked out all process and everything looks fine. I just restart the program and windows and ran machine again. Surprisingly machine works and everything is okay. I am not sure what happened!

Thank you so much for your time,

Milad

Thanks a lot,

Dear mr.white

Thank you so much,

I am not sure what happened, I just restart the program and windows and ran machine again. Surprisingly machine works and everything is okay.

Do you think I can use this method to get back my previous data that lost in the wrong running?

Thanks,

Milad

The data u got from the last run was blank.

You can check if u selected the right signal.

You can try to go to your processing method and select all signal sources on the left hand.

Here u can see that FID1A and FID2B are selected

Maybe u deselect one by accident.

Fantastic!  I'm so happy we were able to get your peaks back.  Often with analyzers, one of the multiple pressure supply modules gets turned off when a cylinder is exchanged, or some type of maintenance is performed.  It is very easy to miss one of the set points when you aren't looking for so many. 

Those manuals are invaluable for troubleshooting, but a re-boot and re-load is a great place to start.  Great work!  There is also a lot of great advice from our peers on this thread, should you run into trouble in the future. 

Best,

Abbey
