Title
(EN) APPARATUS AND METHOD FOR COUPLING TUBING TO CHROMATOGRAPHIC COLUMN
(FR) APPAREIL ET PROCÉDÉ PERMETTANT DE COUPLER UN TUBE À UNE COLONNE DE CHROMATOGRAPHIE
Abstract
(EN)
An apparatus for coupling a liquid chromatography column comprising an end fitting to a tubing comprises: at least one body member comprising at least one chamber; a first spring within the at least one chamber, the first spring configured so as to apply a first force to the tubing towards the column end fitting; a second spring within the at least one chamber, the second spring configured to apply a second force to a deformable sealing member towards the column end fitting; and a pushing and latching mechanism configured to push the at least one body member and the first and second springs towards the column end fitting.
(FR)
La présente invention se rapporte à un appareil permettant de coupler une colonne de chromatographie liquide comprenant une extrémité qui se fixe à un tube. Cet appareil comprend : au moins un élément de corps comprenant au moins une chambre; un premier ressort agencé à l'intérieur d'une ou plusieurs chambres, le premier ressort étant configuré pour appliquer une première force au tube vers une pièce d'extrémité de colonne; un second ressort agencé à l'intérieur d'une ou plusieurs chambres, le second ressort étant configuré pour appliquer une seconde force à un élément d'étanchéité déformable vers une pièce d'extrémité de colonne; et un mécanisme de poussée et de verrouillage configuré pour pousser le ou les éléments de corps et les premier et second ressorts vers la pièce d'extrémité de colonne.
