While using agilent ICP MS 7700 x , following issues are faced. 1-High background for Silicon. 2- for Ca software recommend 44 mass, calibration is linear but quantification is not match with other methods. 3- can l inject 40 % H2O2 direct or after dilution for metal analysis. 4- inject seawater or brine sample direct for low Limit of reporting.
Hi Mohammed Haneesh, Thank you for your application questions using your Agilent 7700x ICP-MS. To allow us to address these specific questions please drop us a note at www.agilent.com/en/promotions/icp-ms-resource and we can discuss your application in more detail.
For organic analysis it is recommended to ignite the plasma in organic mode while aspirating isopropanol (IPA). Tuning and optimization of plasma parameters, lens parameters and ORS parameters should be performed by aspirating a 1 ppb tuning solution prepared from an inorganic Stock Tuning solution (Part No. 5188-6564) diluted in IPA. Please see relevant application note for further information: www.agilent.com/cs/library/applications/5991-3538EN.pdf
The best one I have seen. Thank you very much!
Very good.

What is power cycling was detected in before igniting plasma how can I overcome that problem

How can perform tuning in oil mode
