Calibration Methods 9/12/13 page 3 shown below. The x-intercept of the linear least-squares fit to the data is the negative of the concentration of the analyte in the diluted unknown. The x-intercept can be calculated from the equation for the linear least-squares fit (y = mx + b) for y = 0. Figure 3.1 Standard addition calibration curve In order to see how this result is obtained, recall that ...
