Hello,
Here is an example report with a couple of options for the chromatogram object labeling. The first chromatogram is just the standard object. The second uses filtering to remove all the unknown peaks based on the compound name length. This removes…
Hello Tyler, Can you tell us some more? What are the concentrations you are working with? What settings are you using? It is highly likely that the recovery is low because of the sample preparation. Have you checked with an internal standard addition…
Hello,
We would need more information to diagnose the connection issues. If this is a workstation where both systems are connected directly, I would look at the power settings on the computer. Make sure the computer is not allowed to sleep or shutoff…
Brian,
The only thing you can do in Chemstation is see the signature of the ssizip file in ECM through the ECM properties panel. You cannot sign the files or reports from Chemstation, it has to be done from the ECM client. ECM signatures do not have…
Hi Jchavez
Have a look at this post ( https://community.agilent.com/technical/software/f/forum/6881/correction-factor-scaling-in-ol-from-ez-chrome/23614) that discusses how OpenLab and EZChrom data are scaled differently for different detectors. The…

I finally figured out what was causing the communication error with MassHunter. It was one of the detector EPCs. Once I removed it from the instrument, MassHunter linked up without issue. Would have never imagined that an EPC would cause the issue, so…
Marty,
I need to apologize and thank you at the same time for your patience. I saw your screen grab in your previous response and realized what was the issue. I went back to your video and realized my mistake, too. It appears that the detectors are…
