However I put the tubing in the 2%HNO3 wash sol during the DP.
Thanks]]> Tue, 08 Mar 2011 07:13:08 GMT ICPMS High Oxide low Mg U intensity http://www.scientistsolutions.com/t17923-icpms+high+oxide+low+mg+u+intensity.html Mon, 07 Mar 2011 23:11:50 GMT ICPMS High Oxide low Mg U intensity http://www.scientistsolutions.com/t17923-icpms+high+oxide+low+mg+u+intensity.html Thanks for your reply. After the optimizations and the dual detector calibration we were able to get Mg>50K, In>259K, U>200K and Ceo=2.9 for our daily performance. However we are trying to use the online setup for the internal standard. When we connect the mixing block the CeO = 3.7. Everything else is fine. Is it ok to have higher oxides with the online setup? Thanks in advance for your help

We have an Elan DRCe. I am getting intensities of 50K for Mg 260K for U but 3.4 for CeO. When I lower the neb gas flow CeO is 3.2 or less but Mg<50K and U<200K. My RF is set to 1500. I have new cones. Sample tubing, waste tubing and all other pump tubing has been changed. Neb gas and auto lens optimizations passed. Please help. ]]> Thu, 03 Mar 2011 22:01:28 GMT
