  1. Reliability criteria: (i) the amount of progressive alteration εalt—a systematic (alteration-induced) error; (ii) the intersection with the y-axis (− 1 < δb < 1) and (iii) r2: correlation coefficient of the linear regression. Data in italic represent the mean PI value calculated from the three specimens used in MS experiments
