摘要
采用高效液相色谱仪(配紫外检测器),选择C18柱,检测波长为220nm,以梯度洗脱检测乳酸链球菌素的含量。试验证明,标准曲线有较好的线性关系,该方法回收率达95%,RSD<3.0%,精密度高。
The content of nisin was examined with gradient elution using HPLC of C 18 pillar and 220 nm wavelength. The experiment result shows that there is a fine linear relation in the standard curve, the recovery rate is 95%,RSD〈3.0%, and it is very accurate.
