Hello, I need to archive a file but the file do not archive. It appears the message "Last archive operation failed"
How can I know why the archive failed and how can resolve it?
Thank you
Hello Community
We have a reproducabiility problem on GC-FID's. We run an alkane standard every day in the morning. Peak shapes are looks good but when i compare the total area of the peaks over the last weeks an month, its very bad, i have a standard…
Thanks Marty, I was afraid of that.
Too bad really since piecewise is the most conventional kind of multi-level calibration.
I train using the example of a typical pH meter where they still naturally calibrate at pH 4, 7, & 10. Therefore there…
You can swap out cylinders to do it, but that means a lot more tubing, etc. to purge when you want to run. With the EPC unit, you would simply load the appropriate method to use it and the switch is done at the instrument. Much less tubing to purge and…
Hi
How do I remove FID signal from the report for a dual TCD & FID GC, we use just TCD detector to analyses gas samples and this issue appear yesterday.
open lab rev. C01.05
hi all,
we have ICP-MS 7800 and getting error 1445. The content of the error is as follows:
"1445, Error: Plasma gas flow rate is too low." We can't ignite plasma.
Gas valves and gas line have been checked and there is no problem.
Does anyone…
Hi Agilent,
Due to helium shortage, we need to change carrier gas for our GC-FID. Most documentation for Agilent suggests either H2 or N2, and the Chemstation configuration shows those options as well.
We are considering using argon, however, I…
