微波萃取鳗鱼中磺胺类药物的HPLC测定方法

Detection of Microwave Extraction of Sulfa in Eels by HPLC

采用微波萃取反相高效液相色谱的测定方法对鳗鱼中磺胺类药物的含量进行测定。实验结果表明,采用微波萃取,其方法的分析时间短并可排除其它基质干扰,所用的试剂量少且污染小等优点而具有一定的优越性;与常规的萃取法进行比较,其精密度、重复性及方法的回收率均达到了分析要求。

Having researched the test conditions, we introduced the microwave extraction and set up a system method via HPLC to determine the sulfamethazine and the sulfadimethazine contained in eels. The method shows great selectivity,high sensitivity,good reproductivity. It shortens the length of the test and can obviate the interference coming from impurities as well. Secondly, let's compare the two different extraction methods-regular extraction and microwave extraction. The result shows that with the help of microwave extraction,the preciseness and reproductivity are up to the standard and it is pretty good for recovery.
