Column: Venusil MP-C18 250L*4.6
Mobile phase: 6.3g of ammonium formate in 1000mL, adjust pH to 2.8 with formic acid, Mix well and filter.
Wavelength: 240nm
Procedure: Approximately 0.02 g to 100-mL volumetric flask, dissolve and dilute with mobile phase to volume, and mix, then filter the solution as the test solution.
Inject a volume (about 20 μL) of the sample into the chromatograph, determine the percentage of the major peak by area normalization, record the chromatograms and calculate the peak responses for the major peaks.
