As potential reagents for the determination of traces of selenium by gas chromatography, the compounds 4-fluoro-o-phenylenediamine and 4-trifluoromethyl-o-phenylenediamine have been examined and compared with seven o-diamines previously reported for analytical purposes. Retention times of the fluoro-piaselenols are shorter than all other compounds but, with the electron-capture detector, their responses differ widely. However, the detection limit of the trifluoromethylpiaselenol compares favourably with the commonly used derivative, 5-nitropiaselenol. The analytical requirements of 4-trifluoro-o-phenylenediamine as a reagent, and the results of its application to the determination of selenium in various biological matrices, are presented.
作为通过气相色谱法测定痕量硒的潜在试剂，对化合物4-氟邻苯二胺和4-三氟甲基邻苯二胺进行了研究，并与先前报道用于分析目的的七种邻二胺进行了比较。氟代亚硒醇的保留时间比所有其他化合物都短，但使用电子捕获检测器时，它们的响应差异很大。然而，三氟甲基亚硒醇的检测限与常用衍生物5-硝基亚硒醇相比具有优势。本文介绍了4-三氟邻苯二胺作为试剂的分析要求及其在各种生物基质中硒测定中的应用结果。
