I've consistently had the issue of the EM start up task not running to completion due to: " EM setting failed because of low signal. Check sensitivity with Performance report. "
All the tubing has been replaced, fresh standards have been made, the torch, spray chamber, nebulizer have been soaked in 5% nitric acid. The cones have been deep cleaned with nitric acid and citranox soln (all according to the documentation found online through Agilent).
Current start up procedure is as follows: turn on plasma, signal monitor w/ no gas until the ratios drop below 5% (only the doubly charged ratio starts high and drops), add start up tasks to queue (torch axis, EM, plasma correction, standard lenses tune, resolution/Axis, performance report), signal monitor w/ He gas watching the doubly charged again, add batch to queue.
will attach the most recent performance report and batch report.
The ICP-MS will be professionally serviced by Agilent on Jan 18th 2023. The last service, done last dec, the previous analyst documented that the octupole was serviced/cleaned. Just wondering if this could possibly be an annual issue.
other notes are the RSD are higher too and the reflected power, while running the batch ONLY not during start up, is above 20W at about 23-26.
Any advice or tips would be much appreciated, thank you.
