Title (EN) PROCESS FOR PREPARING LIQUID MIXTURES OF KNOWN PH AND SALT CONCENTRATION
(FR) PROCÉDÉ DE FABRICATION DE MÉLANGES LIQUIDES À PH ET SALINITÉ CONNUS
Abstract: front page image
(EN)A method of preparing a liquid mixture for use in a liquid chromatography system is provided. The mixture comprises one or more acids, one or more bases, one or more salts, and one or more solvents, and the method comprises the steps of : i) calculating pH and/or salt concentration at a particular time t from a user-determined gradient function; and ii) based on the values obtained in step (i), calculating percent acid, percent base, percent salt and percent solvent in the liquid mixture at time t. A liquid chromatography system incorporating such method is also provided.
(FR)Procédé de fabrication d'un mélange liquide pour système de chromatographie liquide. Le mélange comprend un ou plusieurs acides, une ou plusieurs bases, un ou plusieurs sels et un ou plusieurs solvants, le procédé consistant : i) à calculer le pH et/ou la salinité à un moment donné t à partir d'une fonction de gradient déterminée par l'utilisateur ; et ii) sur la base des valeurs obtenues à l'opération (i), à calculer le pourcentage d'acide, le pourcentage de base, le pourcentage de sel et le pourcentage de solvant dans le mélange liquide au moment t. L'invention concerne également un système de chromatographie liquide faisant intervenir un tel procédé.
