استشراب عمودي متماكب
الاستشراب العمودي المتماكب Chiral column chromatography هو تنويعة من استشراب العمود المستخدَم لفصل المتماكبات المتقابلة، كما في الراسمات. The stationary phase contains a single enantiomer of a chiral compound.[1]
The chiral stationary phase can be prepared by attaching a chiral compound to the surface of an achiral support such as silica gel. Common chiral stationary phases are based on oligosaccharides such as cellulose or cyclodextrin (in particular with β-cyclodextrin, a seven sugar ring molecule).
The principle can be also applied to the fabrication of monolithic HPLC columns[2] or gas chromatography columns.[3]
