By detecting amphetamine, methamphetamine and pseudoephedrine under a certain condition, the standard curves were drawn. The standard curve of amphetamine is y = 5.36x −690.98, R = 0.9994. Its linearity range is 2.0 × 102 μg∙mL−1~1.0 × 103 μg∙mL−1. Its detection limit is 2.0 × 102 μg∙mL−1 and its RSD is 9.83%. The standard curve of me- thamphetamine is y = 1.34x + 215.83, R = 0.9980. Its linearity range is 2.0 × 102 μg∙mL−1~2.0×103 −1 2 −1 μg∙mL . Its detection limit is 2.0×10 μg∙mL and its RSD is 6.29%. The standard curve of pseu- doephedrine is y = 8.07x + 176.38, R = 0.9988. Its linearity range is 6.4 × 10−1 μg∙mL−1~4.0 × 102 μg∙mL−1. Its detection limit is 6
