The N=(tR/σ)2 the number of theoretical plates, the distillation the separation of a mixture of two liquids.
The effectiveness of a column is frequently determined using the number of theoretical plates. The range of plate numbers is 100 to 106. The quality of the separation improves with the number of theoretical plates present in a column because more equilibrations between the stationary and mobile phases are possible.
The effectiveness of a column's column is closely tied to theoretical plates in column chromatography. It can therefore help to increase resolution, which, when all other factors are held constant, is directly proportional to the square root of the number of theoretical plates.
