Hello Everyone,
I have been having gradual issues with my sensitivity and low counts on our 7800 ICP-MS instrument. I have cleaned all of the glassware in a nitric soak, cleaned and inspected cones (which are fairly new), cleaned nebulizer (also very new), replaced all pump tubing, remade new tuning solution, replaced a new graphite gasket, replaced bonnet, etc. After no improvement, I navigated through the Agilent low sensitivity tool and still could not pin point the main issue, I will attach performance report history ( you will see how horrible the counts are), and an example of a recent tune report just in case I am not seeing something I should be.
Thank you!
