Agilent Gas Chromatography Supplies & Consumables
Things to consider:
Did you purchase additional required install supplies from Agilent, or will you be providing your own?
Did you purchase sufficient supplies to begin normal operations of the…
Hi,
you can override the mass axis settings, but be advised, that this can cause the loss of counts.
To do a manual mass axis setting do the following:
Go to "Options" and activate "Override Hardware Settings Function in Tune"
In your Batch…
Hello,
For ESTD and ESTD% Chemstation uses the following formulas to calculate compound amounts:
It is not possible to change how these calculations are performed. You would have to perform the concentration calculation you mentioned in the report…
Good morning Serge, today I turned on my ft ir 630 after a few months and I also encountered the same problem as you. Can I ask you how you solved it? Thank you.
Giuseppe
Update: After some investigation, I believe I found the cause of the issue, so I will add it here in case it is helpful to someone in the future.
I mentioned that there are 3 He tanks hooked up to our manifold. For a while there were only 2 tanks hooked…
