We have an ICP system (7800) with a heliumline, a H2 line and a third line for an optional gas, which in my case is Xenon.
I don't remember if a third gasline was standard or optional for the 7800 ICPMS. And I don't know if it is possible to attach…
Hello, I don't have a root cause for you, but we see a similar issue on one particular 7900 where the res-axis auto-tune consistently mal-adjusts. We are using a manual axis offset adjustment as a workaround: In this case your low mass needs +0.05 AMU…
Hello,
This bug is known as the method save bug. This occurs when you are editing the method and do not follow the attached instructions below. Please note, that even if no change is made, but the method is opened in the Edit Method window and saved…

Hi,
Is your tune solution still OK? Maybe the probe is partially blocked? is the amount of mist in the quartz tube (connected to the torch) still the same as always?
Hello,
You could save the result set method as a new name, change it to external standard, and then reprocess just the standards and samples without the IS. I guess my concern is when using an IS in your samples, how it can be missing, that would…
HI Lars,
Yes, you can run the test on a VI. Specific to your system, a failing result could indicate a leak within the inlet or at any of the in-line connections of your GSV, so the results may not be clear without a point leak detector. I would also…
Hi Abdul,
From the picture, it appears your FID flame was extinguished. You can put a metal wrench or a mirror at the top of the detector to see if the exhaust contains moisture from the combustion, but a flat baseline at zero output usually means the…
