Embodiment Construction
[0013] The present invention includes the following steps.
[0014] Weigh the 5F reference substance, add an appropriate amount of methanol to dissolve it, transfer it to a bottle, add methanol to make it up to the mark, and use it as the 5F reference substance stock solution.
[0015] Measure the half-pinner injection and put it into a measuring bottle, add methanol to make the volume up to the mark, and obtain the test solution.
[0016] Put the blank solvent into a measuring bottle, add methanol to make up to the mark, and obtain a negative reference solution.
[0017] Get the reference substance stock solution, the test solution and the negative reference solution, inject samples into HPLC analysis respectively, and record the chromatograms.
[0018] The chromatographic conditions of the HPLC analysis are: the mobile phase is methanol, water, glacial acetic acid; the detection wavelength is 254nm; the flow rate is 1.0mL min -1 ; The column temperature is ...
