Sample Calibration Curve Using Linear Fit
When you inject a sample with unknown amounts of your analytes, you
designate the run as an Analysis Run. After identifying a peak as discussed
above, the peak is quantified using the calibration curve. The peak area, which is
determined after the second step of peak processing, is used as the y value in
the calibration curve equation. This lets you calculate the x value which is the
analyte amount.
External Standard Calibration
The External Standard calibration type is the most common method of calibrating
an analysis. To calculate results with this technique, you must first perform a
calibration run with a standard mixture. The calibration curve manager
automatically generates a curve by plotting the known amounts of standards, as
entered in the Peak Table, against the corresponding peak sizes, as calculated
by the software. When you inject a sample in an analysis run, the Varian MS
Workstation calculates the amount of the analyte from the coefficients for the
curve and the size of the sample peak.
