Abstract: Anew kind of GCcolumn which possesses a tangential gradient in partition ratio was designed.The gradient effects of the tangential column on retention time were investigated.The theoretical equation of the gradient effect was derived. The practical result shows that the gradient effect of retention time on experimental value agrees with calculated value. Since liquid phase on the tangential column is distributed properly, a better gradient effect was obtained and the weakness of the exponential column was overcomed, the tangential column is an ideal column.
