Method for detecting related substances in irbesartan hydrochlorothiazide tablets by adopting high performance liquid chromatography

The invention belongs to the field of pharmaceutical analysis and particularly relates to a method for detecting related substances in irbesartan hydrochlorothiazide tablets by adopting high performance liquid chromatography. The method comprises the steps that 1, chromatographic conditions are firstly determined through a chromatographic column, column temperature, detection wave length and a mobile phase; 2, a test sample solution and a reference substance solution are prepared; 3, a determination method is adopted to perform precision determination of the test sample solution and the reference substance solution respectively, the solutions are injected into a liquid chromatograph, a chromatogram is recorded, and calculation is performed according to a self-contrasting method and a correction factor self-contrasting method; a main peak of the test sample solution and a main peak of the reference substance solution are consistent in retention time, and accordingly the method is achieved. 本发明属于药物分析领域，具体涉及液相色谱
