| titleOfInvention | Method for detecting sulfonic acid phenylhydrazine sulfate series by high performance liquid chromatography |
| abstract | The invention discloses a method for detecting sulfonic acid phenylhydrazine sulfate series by high performance liquid chromatography. The method comprises: 1) the filling material of a chromatographic column is SinoChrom ODS-BP, the mobile phase is acetonitrile and an ion pair buffer solution with a ratio of 10:90, wherein the ion pair buffer solution consists of 1 L of redistilled water, 1.7 g of sodium dodecanesulphonate and 1.0 mL of phosphoric acid, the detection wavelength of a UV visible-light detector is 254 nm, the column temperature is 30 DEG C and the mobile phase speed is 1.0 mL/min; 2) a standard sample is a standard solution prepared by acetonitrile and with a concentration of sulfonic acid phenylhydrazine sulfate series being 0.05-0.3 mg/mL, a to-be-detected solution is obtained by dissolving a to-be-detected sample with acetonitrile and performing ultrasonic filtering; and 3) the standard solution and the to-be-detected solution are injected into the high performance liquid chromatograph, and the chromatogram is recorded and analyzed. The method is simple in operation, high in sensitivity, good in repeatability and reliable in detection result. The method is capable of rapidly and efficiently isolating impurities. |
