## Abstract The time constant, ฯ, is determined from the tail of an authentic HPLC peak through a plot of In U versus time, t, according to the relation expected at low recorder deflexions, U. The value obtained, ฯ = 2.43 s, is one order of magnitude larger than an ordinary recorder time constant

## Abstract In the approach to the developement of a practical procedure for the evaluation of band broadening properties of gas capillary columns, the expression for the variance of a solute band is cast in a dimensionless form. This expression supplies the basis for a valid bench mark for column
It is shown theorectically that the classical formula for calculating the theoretical plate number from squared first central moment, fkg, and second central moment, u2, according to fitheor = f&du2, is valid only when the capacity ratio, E, approaches infinity. The general relation between the clas
