• HETP = height equivalent to a theoretical plate, a measure of the resolving power of the column [m]
• A = Eddy-diffusion parameter, related to channeling through a non-ideal packing [m]
• B = diffusion coefficient of the eluting particles in the longitudinal direction, resulting in dispersion [m² s^-1]
• C = Resistance to mass transfer coefficient of the analyte between mobile [m] and stationary phase [s]
• u = Linear Velocity [m s^-1]

H ：管柱的分離效率

A項：管柱填充物 (定值) 固體顆粒越小， A 值越小，表示物質擴散越低

B/u項：移動項流速,,流速上升則降低

Cu項：質量轉移阻力,橫向擴散係數,固定相薄膜厚度,流速上升則上升
