Separation in Column Chromatography

Dahn and Fuchs [143] have developed a horizontal column chromatography in a cellophane tube, as analogy to TLC. These tubes, approximately 3.6 cm cross-section and 40—45 cm long, are filled with about 300 g especially fine-grained adsorbent. Several columns are joined in parallel in order to separate larger amoimts. Lableb [385] and also Lefemine and Hausmakn [391] have described devices for preparative 

The two-part flat tank of Bbkesy in 1942 [55], subsequently modified by Hall [264], can be regarded as an interesting transition from the circular column to the preparative TLC-layer. It is essentially an S-chamber, filled with an adsorbent (p. 70).

Cyclodextrins (CyDs) show specific complex formation with various guest compounds in aqueous solutions (1). Resins containing CyDs were used for separation in column chromatography (2-4).
