L型~(75)Se-蛋氨酸或DL型~(75)Se-蛋氨酸的无菌溶液,用于肝、胰和甲状旁腺的扫描,进行其病变包括肿瘤的诊断,还可以用来测定动物或人体中蛋白质的转化。~(75)Se蛋氨酸中的主要放化杂质是亚硒酸、砜和亚砜。本工作利用国产滤纸型硅胶薄层片(G)和WhatmanNO.1色层纸(上行、下行以及小型)对~(75)Se-蛋氨酸、亚硒酸、亚砜和砜的薄层色谱和纸色谱行为进行了观察,以期寻找快速、理想的分离方法。 L-type (75) Se-methionine or DL-type (75) Se-methionine for the scanning of liver, pancreas and parathyroid glands for the diagnosis of lesions including tumors, as well as animals Or the conversion of proteins in the body. The main radiochemical impurities in ~ (75) Se methionine are selenious acid, sulfone and sulfoxide. In this work, thin layer chromatography of ~ (75) Se-methionine, selenite, sulfoxide and sulfone with paper made of filter paper (G) and WhatmanNO.1 chromatography paper (up, down and small) Chromatographic behavior was observed in order to find a fast and ideal separation method.
