Yes, the MassHunter software uses a conversion factor and reports in "counts" instead of hertz for uECD data. The conversion factor is 7680.
The 7680 multiplier also applies to other GC based detectors such as FIDs and TCDs.
Hello from Kazakhstan,
Very interesting theme.
I also have some issues with flow method correction and some questions.
1) We use Excel CFT calculator. So how much pressure we should put on calculator, when using SCD detector with FID? As calculator…
Hi,
We are using MassHunter 10.0.368 to collect data on a GC-FID (7890B). The software will randomly crash (the software shuts down with no information in the logbook) during a sequence, usually after 100+ samples. We have updated MassHunter to version…
What you describe with the washes happening, but a delay when pulling up the actual sample for injection sounds like something about the GC is not in a ready state and the GC is waiting for a part of the GC to become ready. In this case you describe it…
First of all, thank you for posting publicly, I had not noticed this interface feature of MassHunter Quant, it looks very useful.
Were you able to get it working in 11.1?
If you're allowed to share your "IScriptable" folder, I would be very interested…
Hi
I am pretty new to GCMS, so may need extra details on how to do things you suggest
I attached a picture of the set up of our gc system, so I can explain better. We recently installed a guard column using 30 cm piece of FS Deactivated 0.250 mm(Agilent…
I have the same problem when the instrument is switched to work at a negative mode. do you think my Medusa power supply also failed? what is the part#? Is G1969-65360 the right part #?
Thanks
The test can be done with or without flow cell. Like I said, the last test didn't look awfully bad to me (remember, a failed test in LabAdvisor doesn't necessarily indicate a real problem or even hardware failure).
Check your environmental conditions…
Hello !
I interesting gc8890 and gc7890.
In datasheet the gc 7890 writing about posible instal 3 detector maximum, but in datasheet gc 8890 writing about posible 4 detector. I never see 4 detectors are installed simultaneously on one chromatograph…
James, Thanks again. Actually, at first we had "EPC or detector error” and we tried to clean the detector but with no change. Once the GC says “Ignite, ignite” the error pops out. We tried second module (the refurbished) and at first we were receiving…
