Two problems in the solution of the generalized equation for the integral retention effect in gas chromatography

Abstract

Two problems arise from the solution of the generalized equation describing the integral retention effect: a direct problem to calculate the integral retention effect when the specific phase characteristics and the partial partition coefficients are known; and an inverse problem to determine the partial partition coefficients when the integral retention effect and the specific phase characteristics are known. A matrix representation of the generalized equation for the integral retention effect is derived. Due to its greater importance for the theory and the practice of gas chromatography only the solution of the inverse problem is described. For this problem the developed matrix approach has been used. An appropriate computation program has been written in the algorithmic language “Gier Algol 4” and used in a digital electronic computer “Gier”. The examples are selected from the experimental data published byPecsok et al [3].
