ICPMS 7850 Low sensitivity


We have been having issues with our ICP MS performance and tune reports. Both have been failing with low counts. We have changed the peri-pump tubing, remade all standards, remade the tune solution, replaced the torch, and cleaned the cones. We have gone through the Agilent troubleshooting guide and are receiving low counts the 12 56 80 test as well. What next steps should we take to correct this?

Thank you.
