Title
(EN) METHOD AND APPARATUS FOR RAPID DETERMINATION OF POLYMER MOLECULAR WEIGHT
(FR) PROCEDE ET APPAREIL PERMETTANT DE DETERMINER RAPIDEMENT LA MASSE MOLECULAIRE D'UN POLYMERE
Abstract
(EN)
A rapid analysis method for the determination of polymer average molecular weight separates the polymer's high molecular weight fraction and determines its average molecular weight using a molar mass detector and a concentration detector. The method avoids time consuming sample preparation, allows for separation of interfering low molecular weight components, and is suitable for automation.
(FR)
L'invention concerne un procédé d'analyse rapide permettant de déterminer la masse moléculaire moyenne d'un polymère, consistant à séparer une fraction élevée de la masse moléculaire du polymère et à déterminer sa masse moléculaire moyenne à l'aide d'un détecteur de masse molaire et d'un détecteur de concentration. Ce procédé permet d'éviter une longue préparation d'échantillons, il permet de procéder à la séparation des composants à faible masse moléculaire interférents, et il est adapté à l'automatisation.
