The accuracy profile method

The results summarized in the table Fidelity parameters and calculation of dispersion intervals for the three concentration levels can be used for an initial graphic illustration, such as the one shown in Figure Accuracy profile represented from absolute values. It can be seen that most of the dispersion interval (solid lines) lies within the limits of acceptability (dotted lines). However, this graph is difficult to interpret, as the different series are almost confused, especially for the lowest concentrations of particular interest to us.
