Hello Everyone, I'm new to Open Lab CDS and I currently have version 2.2 paired with a Agilent GC-FID. I'm still learnng the software and I had a few questions in regards to calibrating and calculating uncalibrated peaks. In Open Lab CDS, how do I calculate…
Ok. So it sounds like some progress to get the negative mode tune to complete and look ok. I would run the negative tune only. Let it complete and save the tune file. Then run a positive polarity tune immediately.
If that fails again, its probably worth…
The front inlet on my GC8890 is failing the restriction test. It passes the leak test no problem and I've done everything I can think of to fix it. I've replaced the septa, checked the gold seal, trimmed the column, baked the column, and checked the inlet…
Related question. Simple GC with a valco rotary valve, 10 position, 6 position, whatever. what is the scfm requirement for that pneumatic device over the course of a method run where after half a minute the valve switches, then 15 minutes later switches…
It's best to set the system to vent and turn off the power first. You do not need to actually vent it/open the MS.
Lift off the analyzer cover as shown.
Remove the three T-20 screws at the red arrows.
Then the entire side panel will pivot out…
Good afternoon everyone,
We are performing the media replacement accuracy test in our 850-DS Dissolution Sampler Station and our test is failing (specification <=9mL), as per table below:

Hi everyone, hoping I can get some help with this, as I've tried many solutions and so far nothing has worked longer than a few hours. I'm running at 7890A with 5975C MS. Yesterday morning, Instrument Control froze after running our opening standards…
Than you should probably stop advertise it as a sulfur-specific filter on specs table (add "and hydrocarbons" words) https://www.agilent.com/en/products/lab-supplies/chromatography-spectroscopy/gas-management/gas-clean-purification-syste… . Otherwise…
By chance is your TCD plumbed to your FID, non destructive to destructive detector configuration? Or using a splitter device of some type? A picture from inside the oven would help. Have you tried the split vent maintenance yet? I would do this even without…
