Abstract

L'invention porte sur une clé de fixation pour une colonne de chromatographie, ladite clé étant constituée d'un ensemble de mise sous tension (13) et d'un ensemble manchon de connexion (12). L'ensemble de mise sous tension comprend un boulon à vis (8), un manchon de mise sous tension (9), une broche de tension (10), un élément plat fraisé (15), et une fente (16). L'ensemble manchon de connexion est constitué d'un manchon de connexion (6), d'un élément en saillie (7) et d'une poignée (5). L'élément en saillie est disposé à une extrémité inférieure de l'ensemble manchon de connexion et est inséré dans un trou (11) au niveau d'une extrémité supérieure du manchon de mise sous tension pour former une clé de fixation à usage spécial pour une colonne de chromatographie. En utilisant la clé de fixation ci-dessus, il n'est pas nécessaire de former un trou ou évidement au niveau d'une surface d'une ferrule de fritte (1), de sorte qu'au contact d'un échantillon et d'une phase mobile, il n'y ait aucun angle mort, de sorte que la surface de la ferrule de fritte puisse être nettoyée facilement. De plus, la clé de fixation peut être directement utilisée au-dessus d'une fritte sans qu'il soit nécessaire de la placer sous le capuchon d'extrémité d'une colonne de chromatographie, ce qui permet d'éliminer les limitations sur une hauteur globale de la colonne de chromatographie, et de réduire les coûts de production.
