A high-pressure liquid chromatographic procedure for the determination of sulfamethazine residues in beef tissues is presented. Tissue samples are extracted and analyzed utilizing normal-phase chromatography and a UV detector at 254 nm. Primary and confirmatory identification and quantitative determination are provided at the tolerance limit of 0.1 ppm of sulfamethazine in tissues. Recoveries obtained from liver, fat, kidney, and muscle tissues were 69, 82, 77, and 76%, respectively, when spiked at the tolerance limit.
本文介绍了一种用于测定牛肉组织中磺胺二甲嘧啶残留量的高压液相色谱法。利用正相色谱法和254nm的紫外检测器对组织样品进行提取和分析。在组织中磺胺二甲嘧啶的耐受限度为0.1ppm时，进行初步和确证鉴定以及定量测定。当在耐受限度添加标准品时，从肝脏、脂肪、肾脏和肌肉组织中获得的回收率分别为69%、82%、77%和76%。
