The linear regression equations were obtained by plotting the experimental peak area ratios of d0-MASC/d3-MASC derivatives (y) against nominal concentration ratios (x).
Slopes of regression equation of calibration curves for the seven derivatives approximated to 1.0, the correlation coefficient values (R2) of above 0.99 were obtained for all the analytes, indicating good correlation of the experimental data with the theoretical ratios (See Supplementary Material Fig. S3).
