MODIFICATION OF THE H-ROOT METHOD FOR THE DETERMINATION OF MULTICOMPONENT LANGMUIR COEFFICIENTS IN LIQUID-CHROMATOGRAPHY

A refined version of the h-root method is presented for the measuremen t of Langmuir equilibrium coefficients in liquid chromatography. As in the original method, the measurement is based on the column behavior in the frontal mode. However, in the present case only frontal capacit y factors are required, as opposed to the original requirement of a co mplete effluent composition history. It has been shown that this refin ement significantly reduces the experimental effort required for the m easurement of the equilibrium coefficients.
