%X In this paper, the characteristics of separating xylitol, arabinitol and sorbitol with uniformly loaded columns containing 2,5,7 and 9wt% XE-60 and gradient loaded columns are compared in detail. The suspended chain curve formulaY=en (x-a/2) e-n (x-a/2) is suggested for calculation of amount of different coated packing in the gradient loaded column, where selector coefficient n=l.l, a is average liquid loading amount, x is individual liquid loading amount. The gradient loaded column can not only satisfactorily separate isomers of xylitol and arabinitol, but also shorten retention time of sorbitol obviously.
