【摘要】 目的:建立高效液相色谱法同时测定食品中4种添加剂(苯甲酸、山梨酸、糖精钠、乙酰磺胺酸钾)的方法。方法:选择相同的流动相和检测波长,采用适当的沉淀剂,对四种添加剂的检测条件进行了优化。结果:在甲醇-0.02mol/L乙酸铵(5/95,v/v)为流动相,流速1mL/min,检测波长230nm的条件下,四种添加剂可得到很好的分离。更多还原

【Abstract】 Objective: To establish a method for simultaneous determination of four additives (benzoic acid, sorbic acid, saccharin sodium and accesulfame potassium) in food by HPLC. Method: Same mobile phase and detection wavelength were selected and suitable precipitating agent was used. The HPLC conditions were optimized. Results: With mathanol-0.02 mol/L ammonium acetate as mobile phase, flow rate at 1 mL/min and detection at 230 nm, four additives can be separated satisfactorily.更多还原
