Abstract
Disclosed is a ceramic body for chromatography, which consists of a calcined molded body of alumina particles composed mainly of .alpha.-alumina, preferably containing a minor amount of .gamma.-alumina, and which has a narrow pore size distribution range. This ceramic body has no substantial adsorbing property and therefore, when it is used for use like to thin layer chromatography or gas chromatography, the tailing phenomenon is not caused to occur at all and a high separating capacity can be obtained stably.
