New Moment Equations in Chromatography

Аннотация

The exact solution obtained for the direct problem of chromatography within the model of an equilibrium adsorption layer using the integrand of the Euler γ-function has been analyzed. Analytical solutions have been presented for the first three temporal, two normalized, and two central moments as functions, which are represented by one-term fractions and comprise the length of an adsorbent layer, mobile phase velocity, effective kinetic constant, and Henry constant. The new moment equations substantially differ from those being used at present.
