I have observed that when a method is transferred to a new system, you need to save it in the new system before using it. If you just copy the method and use it, sometimes it fails. Just by saving it, it makes it work. I guess it saves some defaults from…
We have an LC-MS with an Agilent 1260 Infinity HPLC stack, with a G7167A multisampler. The multisampler has one drawer installed with 2x 54-vial plates. We have had some communication issues recently where the transport initialistation kept failing after…
What are the detector voltages? Select the Hardware button, or Hardware/Dashboard from Task manager, and click the Detector image. Select EM setting. What are the voltages for Discriminator, Analog HV, and Pulse HV?
Was the instrument off, for an extended…
it does not work,
I tried to install openlab v2.4 manually, the installation failed at the agilent platform in the install or upgrade content management part,
The Agilent LabAdvisor software shows the Xe lamp life time, but in percent, not in hours. This is because of a fairly complex calculation, taking the amount of high or low power flashes into consideration. The higher the number, the more worn the lamp…
Hi Lycrecia,
We checked the volume calibration section and we did the full range volume dispense, as described in the manual. However, we are not sure which value we should add to the actual volume in the volume calibration screen. Do we need to do…
Hello, Your question brings some additional questions for me. You mentioned that your rescans are failing eventhough the product is correct. Is your method robust enough. You should not see many fails in a batch if the instrument is properly operated…
It is great you have such a nice experience with your results, however results accuracy is a matter of hardware robustness and method setting, not software. I your insist on this, I can recommend you to do the following steps:
1- get the licence number…
Hello, To cut to the chase: No, peak areas calculated in MassHunter will not be equal to the peak areas calculated in GC/OpenLAB ChemStation software. GC ChemStation and OpenLAB ChemStation use response units of pA for FID data whereas the response axis…
Hi, My method for 6890 GC/FID has a warning message that there are overlapping integrations for some of the compounds, I would like to correct this but unsure how, I know the answer lies in the integration events table. Any help is appreciated!
