Title
(EN) MULTI-COLUMN SEQUENTIAL SEPARATION PROCESS
(FR) PROCEDE DE SEPARATION SEQUENCE MULTICOLONNES
Abstract
(EN)
The subject of the invention is separation on a solid support by multi-column sequential selective retention in order to separate a product of interest from a solution containing such a product of interest, by passing this solution over a fixed chromatographic resin bed comprising at least three zones, liquid flow means being placed between adjacent zones and between the last zone and the first zone, this process comprising several sequences, each sequence comprising at least one step chosen from an absorption step, a rinsing step and a desorption step, carried out either simultaneously or not, each following sequence is carried out by the displacement of the fronts in the zones towards the downstream end substantially of the same increment before the periodic displacement of the points of introduction and of withdrawal, characterized in that the process includes a sub-sequence without injection of the charge.
(FR)
L'invention a pour objet un de séparation sur support solide par rétention sélective séquentiel multicolonnes pour séparer un produit d'intérêt à partir d'une solution contenant un tel produit d'intérêt, par passage de cette solution sur un lit fixe de résine chromatographique et comprenant au moins trois zones, des moyens d'écoulement de liquide étant disposés entre des zones adjacentes et entre la dernière et la première zone, ce procédé comprenant plusieurs séquences, chaque séquence comprenant au moins une étape choisie parmi une étape d'adsorption, une étape de rinçage, une étape de désorption, mise en œuvre de façon simultanée ou non, chaque séquence suivante est effectuée par le déplacement des fronts dans les zones vers l'aval sensiblement d'un même incrément avant le déplacement périodique des points d'introduction et de soutirage caractérisé en ce que le procédé comprend une sous-séquence sans injection de la charge.
