Abstract
FROM the preparative aspect, the conventional paper chromatographic technique is rather limited, in that only a few micrograms of material can be spotted on a single strip or sheet, and the labour involved in the separation of even milligram quantities in this way is enormous. From this point of view the circular paper chromatographic technique1 offers great possibilities. By a suitable modification of this technique, it has been found possible to obtain from a single chromatogram material of individual components from a mixture of sugars sufficient for the determination of physical constants and preparation of characteristic derivatives.
