Setting the Internal Standard Correction
ChemStation allows you to set an internal standard for each element.

internal standard will not be quantitatively analyzed.
The CPS of an analyte can be corrected based on the value (VIS) calculated using an
interpolation formula without changing the existing internal standard correction.
The internal standard correction can be set using the following procedure.
NOTE If an internal standard is not added to the standard sample and sample, the following
step is not necessary.
1 Select an interpolation formula in the Mass Interpolation Fit: drop-down list in
the upper right section of the Edit Calibration dialog box.
Refer to “Interpolation Formulas for Virtual-Internal-Standard Correction” in
“Quantitation” in Appendix B “Formulas.” for details on interpolation formulas.
NOTE If VIS is not used, it is not necessary to select an interpolation formula.
