CWS1.0色谱工作站测定微量发硒

Determination of Se in Hair by CWS 1.0 Chromatography Work Station

利用硒与4-硝基邻苯二胺在硫酸和高氨酸溶液中生成5-硝基-2，1，3-苯并硒二唑，且可被萃取至甲苯中的性质，用气相色谱法配合电子捕获检测器测定了甲苯中的5-硝基-2，1，3-苯并硒二唑，从而测定了硒的含量，数据处理采用自行研制的CWS1．0色谱工作站进行，可对样品采集文件进行多种处理。操作快速、简便，处理结果精密、准确。该法用于人发中微量硒的含量测定，获得了满意的结果。

The trace element Se in hair was determined by CWS 1.0 chromatography work station with ECD. Se can be combined with 4-nitro-Dephenylene diamine for making out 5-nitro-2, 1, 3-Se-benzimidazole which can be extracted into methyl benzene. By 5-nitro-2, 1,3-Se-benzimidale testing, the content of Se can be detemined.
