Question on ICP-MS spray chamber drainage
Posted: Wed Apr 15, 2009 5:31 am
Hi,
i am running an agilent ICPMS4500 with a self aspriating concentric nebulizer.
i notice that the spray chamber drainage in this systems is different from others.
Accroding to the manual, the waste drainage should be small volume in short regular interval however for this system the drainage is large volumes in long intervals.
i have washed and clean the chamber and changed the pump tubing but this still occur. Anyone knows what is wrong with the system?
FYI. i am using an all plastic sample introduction because of HF.
