Once the standard solutions have been analyzed, the calibration curve must be plotted, which will be a straight line if it is within the instrument’s linear range (and if the standard solutions have been prepared correctly). If a calibration point deviates from the straight line, it may be useful to remake the standard solution concerned.

Either concentrations or quantities can be used to plot the calibration line.
