The tartaramide based chiral selector 2 was synthesized, coated onto porous graphitic carbon (PGC), and evaluated as a chiral stationary phase for HPLC. Its performance was compared to the silica based sorbent 1, containing the same chiral moiety. The retention and separation characteristics of the two columns were found to be correlated, but separation factors and column efficiencies were constantly
合成了基于酒石酰胺的手性选择剂2,将其涂覆在多孔石墨碳(PGC)上,并评价为HPLC的手性固定相。将其性能与包含相同手性部分的二氧化硅基吸附剂1进行了比较。发现两个色谱柱的保留和分离特性是相关的,但是PGC色谱柱的分离因子和色谱柱效率始终较低。评价了PGC的涂层作为评价手性选择剂的新颖和简单的方法。
