Chiral chromatography principle
WebThe development of methods for chiral separation on an analytical as well as on a preparative scale has attracted great attention during the past two decades. Chromatographic methods such as gas chromatography (GC) (1), high-performance liquid chromatography (HPLC) (2–6), supercritical fluid chromatography (SFC) (7–9), and … WebThe most abundant and popular chiral GC stationary phases are α-, β-, and γ-CDs (see Fig. 11.2 ). The shape of CD molecules is like a hollow truncated cone. (see Fig. 11.3 ). Each glucose unit has three OH groups (2-OH, 3-OH, and 6-OH). The 2- and 3-OH groups are secondary hydroxyl groups and are present at the wide end or “mouth” of the ...
