Title (EN) METHOD AND APPARATUS FOR ADJUSTING AVERAGE COLUMN PRESSURE IN A CHROMATOGRAPHY SYSTEM TO APPROXIMATE AN IDENTIFIED AVERAGE COLUMN PRESSURE
(FR) PROCÉDÉ ET APPAREIL POUR AJUSTER LA PRESSION MOYENNE DE COLONNE DANS UN SYSTÈME DE CHROMATOGRAPHIE POUR APPROCHER UNE PRESSION MOYENNE DE COLONNE IDENTIFIÉE
Abstract:
(EN) Methods for transferring a carbon dioxide based separation procedure from a first chromatographic system to a second one are disclosed. An average column pressure for the separation in the first system is identified. A measured average column pressure for the separation in the second system is determined. The measured average column pressure is compared with the identified average column pressure. To more closely match the identified average column pressure, the methods involve one or more of: (a) altering the flow rate of the mobile phase in the second system; (b) altering the composition of the mobile phase in the second system; and/or (c) adding a restrictive element between the inlets of a first column and the detector in the second system.
(FR) L'invention concerne des procédés permettant de transférer une procédure de séparation à base de dioxyde de carbone d'un premier système chromatographique à un second système chromatographique. Une pression de colonne moyenne pour la séparation dans le premier système est identifiée. Une pression de colonne moyenne mesurée pour la séparation dans le second système est déterminée. La pression de colonne moyenne mesurée est comparée à la pression de colonne moyenne identifiée. Pour correspondre plus étroitement à la pression moyenne de colonne identifiée, les procédés impliquent une ou plusieurs des étapes suivantes : (a) modification du débit de la phase mobile dans le second système; (b) modification de la composition de la phase mobile dans le second système; et/ou (c) ajout d'un élément restrictif entre les entrées d'une première colonne et le détecteur dans le second système.
