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…
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…
I was never able to do glycols via headspsce in the past. The only way I was able to do them was direct injection and FID. 5890 using megabore column. Maybe you could try SPME.
I am running GC 6890 (FID detector) alongside G1888 headspace.
I had noticed 4 of my later eluting peaks got increasingly worse in terms of shape and reproducibility. After running blanks (no injection and also blank vials), it seemed like the cause…
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…
This is a 5977A that was built in mid-2015. How many runs on it? . High Energy Dynode (HED) related, Electron Multiplier (EM) related, signal related, or electronics related.
The first thing to try is to go into manual tune and turn OFF the HED. I'd…
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,
Good Morning, Just setup a 7890B GC with Empower 3 for the CDS Built an instrument method to use both the front and back injection ports. I have a 6890N with front and back FID that we run a lot of samples on so this isn't a new method development. +…
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…
Hello Andy, thanks for your answer. It would be possible, however we would like to automate our analysis as much as possible. A manual calculation of the concentrations, depending on the initial weight, would make us go a step in the wrong direction.…
