| titleOfInvention | A method for analyzing cathinone substances in dried blood samples |
| abstract | The invention relates to a method for analyzing cathinone substances in dried blood samples, comprising the following steps: step S1, preparation of standard sample solution; step S2, preparation of internal standard solution; step S3, preparation of sample solution; step S4, setting of detection conditions; step S5, liquid chromatography-mass spectrometry determination; step S6, calculation of experimental results; wherein, in step S3, a certain amount of whole blood is spotted on cardboard, protected from light, and dried at room temperature , use a punching device to remove the dried blood sample, dissolve the dried blood sample in buffer to form a solution, add ethyl acetate to the solution, centrifuge, take the supernatant and dry it, redissolve it in methanol to form a sample solution . The advantage is that the DBS method is used to detect cathinone substances, and the advantages of DBS, such as the convenience of storage and transportation and the small amount of blood samples required, reduce the use of blood samples and reduce the cost of blood; and the use of organic solvents is less, Effectively reduce environmental pollution. |
