摘　　要：建立一种方便廉价且耐用的高效液相色谱法,以亲水柱ZORBAX SB-Aq(4.6 mm×150 mm,5μm)为分离柱,甲醇-水为洗脱液,流速0.8 mL·min-1,柱温30℃,时间10 min。此方法操作简单,检测时间短,检测成本低,重复性良好。本文研究了不同模拟液和不同温度对三聚氰胺迁移量的影响,结果表明,酸类模拟液易导致三聚氰胺迁移,温度越高迁移量越大。Developed a convenient,inexpensive and durable HPLC method.Using a hydrophilic column ZORBAX SB-Aq(4.6 mm×150 mm,5μm)as a separation column,Methanol-water was used as the eluent,the flow rate was 0.8 mL·min-1,the column temperature was 30℃,and the time was 10 min.The method has the advantages of simple operation,short detection time,low detection cost and good repeatability.The effect of different simulated liquids and different temperatures on melamine migration was studied by this method.The results show that the acid simulating liquid is the most likely to cause melamine migration,and the higher the temperature,the greater the migration amount.
