Calibration Curves

Use calibration curves to find the calculated concentration of samples, including QC (quality
control) samples. QC samples are added to a batch to estimate the data quality and accuracy of
standards in the batch. QC samples have known analyte concentrations but are treated as
unknowns so that the measured concentrations can be compared to the actual value.
The calibration curve is generated by plotting the concentration of the standard versus its area or
height. If an internal standard is used, the
versus the ratio of the standard peak height or area to the internal standard peak height or area is
plotted. The area or height ratio of a sample is then applied to this curve to find the concentration
