According to the determination of high performance liquid chromatography (General 0512), with eighteen alkyl silane bonded silica gel as filler; Acetonitrile -5mmol/L ammonium acetate solution (containing 1% triethylamine, using glacial acetic acid to adjust the pH value to 5.0±0.5(65:35) as mobile phase; The detection wavelength was 214nm. The degree of separation between the C12 peak and the C14 peak of benzalkonium chloride shall meet the requirements. 20 u1 of each of the reference solution and the test solution were accurately measured and injected into the human liquid chromatograph respectively, and the chromatogram was recorded. According to the external standard method to the peak area calculation, this product per lml containing benzalkonium chloride shall not exceed 0.12mg. Osmolality of this product, according to the law to check (General 0632), osmolality ratio should be 0.9~1.1.
sterile take this product, dilute with pH 7.0 sterile sodium chloride-peptone buffer 200ml, after membrane filtration treatment, rinse with pH 7.0 sterile sodium chloride-peptone buffer (not less than 200ml per membrane), staphylococcus aureus as a positive control bacteria, according to law inspection (General 1101), should comply with the provisions.
others shall comply with the relevant provisions under Ophthalmic Preparations (General rule 0105).

Content determination

measured by high performance liquid chromatography (General 0512).
chromatographic conditions and system applicability test using eighteen alkyl silane bonded silica gel as filler; Methanol -4% glacial acetic acid solution (70:30) as mobile phase; The detection wavelength was 276mn. Take an appropriate amount of diclofenac sodium, add water to dissolve and dilute to make a solution containing about 1 mg per 1 ml. Take an appropriate amount of the solution and expose it to UV lamp (254nm) for 15 minutes, A 20ul injection liquid chromatograph is taken and the chromatogram is recorded. An impurity peak appears at about 0.8 relative retention time to the main peak, and the separation degree of the two should be greater than 4.0.
determination Method: Take 5 bottles of this product, mix well, take 5ml accurately, put it in a 25ml measuring flask, dilute it to the scale with 70% methanol, shake well, filter, the filtrate was continued as a test solution. Take 10ul accurately, inject human liquid chromatograph, record chromatogram; Take appropriate amount of diclofenac sodium reference substance, accurately weigh, add 70% methanol to dissolve and quantitatively dilute to make a solution containing about 0.2mg per lml, same method determination. According to the external standard method to calculate the peak area, that is.
