Argon quality for the Agilent 700, 5100 and 5110 icp-oes systems is 5.0 or better. However the 5800/5900 will work with the 4.5 (99.995%) argon quality. For the optional oxygen addition, needed for some organic matrix measurements like kerosine a mix…
Hi, yes we did resolve the issue and it was a faulty Z-motor. Motor was replaced and "Z-axis" error went away. The "unexpected collision" error was due to me using the wrong vial bottoms with the vial tray I had. I needed to use rounded bottoms instead…
Hello Martin and Andy! I found out what were wrong. In my sequence two injections doesn't have a DA Method linked. When I pin only the injections with DA Method linked, the "No Data Found" was gone.
Thanks for letting us know. I will look into this and determine why it is not working. In the meantime, the file can be downloaded from the 7820A product page at https://www.agilent.com/en/product/gas-chromatography/gc-systems/7820a-gc-system . Scroll…
Thank you very much for your quick answer. It's very important for me to understand the concept well, so I have some consistency problems with the response of the compounds.

Hello,
Are you still having low flow issues on your AA? Did replacing the nebulizer assembly help?
Do you change the flame gases for your methods? If so, call up a default air/acetylene method. You will need a lamp of that element. Go to Optimize…
