Two quantification strategies for one-point standard addition calibration have been compared mathematically. One strategy involved the extrapolation of measurement points to their intercept with the x-axis to determine the analyte content in the unknown sample, and the other strategy is based upon direct calculation of the analyte content in the unknown sample using the analytical intensities obtained during measurement. The cases of both conventional standard addition calibration (C-SAC) and sequential standard addition calibration (S-SAC) have been considered. The homoscedastic situation has been considered, where the absolute precision of analytical intensities is constant. It has been determined that the precision ratio of the two strategies is dependent on surprisingly simple parameters: such as the mass ratio (for C-SAC) and the analyte content ratio (for S-SAC).
