Correcting Responses for All Elements

After you have loaded the data file and entered concentration values for the
calibration elements, you can view the responses for all other elements.
The procedures in the following 8 sections assume that you are in the Edit SemiQuant
Parameters dialog box. For information about accessing this dialog box, see
"Entering Concentration Values" in this chapter.
To view responses for all elements, complete the following step:
Click Correct by Current Data.
The corrected response values change and counts per second (cps) values appear for
all elements normally analyzed by ICP-MS. The original response values remain
unchanged.
The number of counts detected for the most abundant POINT of all points measured
for the semiquant mass is used in calculating the SemiQuant Factor. This value can
be examined by selecting Spectrum>>Tabulate / Point... within Data Analysis, if
desired.

Resetting the Response Values

ChemStation enables you to reset the original response values. To do so, complete
the following step:
Click Reset Correction.
ChemStation changes the corrected values to the original response values.
