有关手性物质%ee的测定?本人对色谱一知半解,在阅读文章中表格的备注:“c. Starting % ee of R-(-)-mandelic acid is 76.1%; the ee of samples were determined by the aomparison of HPLC profile with authentic samples”时,对后半句话,有疑惑。用手性HPLC,测出一对 对映异构体 的峰面积,两者相减难道不是ee数值吗。为何还要用 标准物质 对比啊?如果用标准物质对比,怎么对比,计算分析,求真相!另外,简单介绍文献背景,研究不同固定相(手性,非手性)对手性物质分离的效果的影响。查看更多4个回答 . 13人已关注
文献中将bulk Pt与Pt基催化剂的电催化性能进行对比,一直没有明白 bulk是什么意思?文献中将bulk Pt与Pt基 催化剂 的电催化性能进行对比,一直没有明白 bulk是什么意思。是体相Pt或者Pt丝电极?出处:To our knowledge, the ORRkinetics on Pt/TiO2-FGS prepared in this manner have never beenreported before, and this is the first comparison of ORR kineticswith that of polycrystalline bulk Pt and commercial Pt/C catalyst.? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?——K.
