| Abstract:Objective To establish a HPLC-ECD method for determination of nitrite remaining in gliclazide. Methods A colum of Hypersil-SAX was used. The mobile phase was 13.61g of sodium acetate dissolved in water(pH4.3) with phosphoric acid and diluted to 1000mL. Results The linear range was 0.04～0.80μg(r= 0.9995). The average recovery was 99.2% RSD = 1.7% (n = 9). Conclusion The method was simple and accurate. |
