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.

Hi Milad,

I looked at the method and data files and don't see anything wrong with them.  It is a bit unusual that you have the front detector listed as signal 2 and the back detector as signal 1 but there is no reason you can't specify it that way.

Since you are using a headspace there are all sorts of things that can cause no peaks (plugged lines / leaking lines / bad valves).  Can you confirm that you see peaks for the signals on the "Online Plot".  The data files look very much like blanks.

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 Tim,

Thank you so much for your message,

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

Thanks a lot,

Milad

Dear mr.white

Thank you so much,

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.
