作者研究肉类、奶粉中磺胺(HA)、磺胺嘧啶(HAMD)、磺胺二甲嘧啶(HALJMD)、磺胺甲恶唑(HAJWZ)四种磺胺药物提取、纯化和定性定量的高效液相色谱(HPLC)条件,建立了HPLC法测定肉类、奶粉中四种磺胺药物残留量的方法。四种磺胺药物在鸡肉、奶粉中三个水平的添加回收率在90.4%～97.9%之间。三个不同水平的样品测定(n=7)相对标准偏差为1.9%～7.6%。本法的线性范围为0.04μg/g～2.0μg/g。最低检出浓度为0.002μg/g。
The authors studied the extraction, purification, and qualitative and quantitative high performance liquid chromatography (HPLC) of four sulfonamides, including sulfa (HA), HAMD, HALJMD and HAJWZ in meat and milk powder ) Conditions, the establishment of HPLC method for the determination of meat, milk powder four sulfa drug residues. Four sulfa drugs in chicken, milk powder in the three levels of the added recovery was between 90.4% ~ 97.9%. The relative standard deviation (n = 7) of three different samples was 1.9% ~ 7.6%. The linear range of this method is 0.04μg / g ~ 2.0μg / g. The lowest detectable concentration was 0.002 μg / g.
