Hello,
Can someone tell me please how to assign some elements to be corrected by internal standard, and skip other elements ?
them. I have an Agilent 725 ICP-OES with Expert II software.
Thanks in advance.

Hello tpcardinal,
that was very helpful! thanks a lot
I actually have another question, do you know by chance how the internal standard is used in the calculation/generation of calibration curve and how it is used in the unknown samples as well ? I calibrate using Yttrium IS online and a multi-elements std solution that I dilute to 2, 5, and 10 ppm including a blank, I choose weighted fit, no force thru blank for the calibration curve. In sequence I set the mass of the sample and the total mass after dilution, I don't include the dilution factor. The results showed the Y internal S as ratios which full down a long the run. Not sure if the Y ratios are included in the elements concentration calculation and what kind of equation is implemented in the software (EXpert II icp-oes 700 seris) ?
Thank you in advance.
