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…

ryoboyle I am struggling with the same question. How do I manually enter response factor? I am also wanting a % recovery column or difference between acquired value and true value. Also, should it not be Response/Amount?
Hi Monty,
Could you provide a little more information on this? Are you talking the bias created when using weighted fit, or is there an issue in the low count standards compared to the rest of the curve?

Hello,
Have you been able to resolve this?
The cones do not affect the pressure required to get the instrument turbo pump to come on and get to standby mode. They only become an issue when lighting plasma and when the interface valve opens.
Most…
Never mind, just discovered how.
For future reference, right-click over the samples and select "Reject Settings", a pop-up appears allowing to select which replicates to reject.
And moved again to the forum where it belongs :-)
Hi ByCoder,
if you want reproducible results NEVER clean liners and reuse them. Any cleaning process will remove the deactivation layer for GC/MS (UI) liners, glass wool has a different deactivation…
