Plate Theory and Extensions - Temperature Changes During the Passage of a Solute Through a Theoretical Plate in Gas Chromatography > Page 88



Under adiabatic conditions, b=0 and


Thus, when there is no heat lost from the plate, the temperature profile of the plate will take the same form as its concentration profile.

When w >3, the solute band will have virtually passed through the plate and


Thus, when w >3 and the temperature of the plate is recovering, equation (39) becomes



where                         .
