Abstract

Système servant à produire une composition programmée de liquide, notamment pour la chromatographie liquide à haute pression permettant de réaliser une programmation quelconque de la composition d'un liquide à trois composants Le récipient 4 et la conduite 3 du liquide refoulé sont reliés aux vannes électromagnétiques à deux voies 6. Les batteries 7 et 7' sont reliées aux conduites d'amenée 9a et 9b de la vanne électromagnétique à trois voies 8, et la batterie 7'' à la conduite d'amenée 9a' de la vanne électromagnétique à trois voies 8'. Ces vannes sont reliées entre elles par l'intermédiaire de la conduite d'amenée 9b' et la conduite de sortie 10 et sont connectées, ainsi que les batteries avec un système électronique de commande 12; la vanne 8' est reliée au mélangeur 11 par l'intermédiaire de la conduite de sortie 10'. Les vannes possèdent une chambre équipée d'un aimant monté dans une enveloppe en téflon, limitée par deux vis munies de bobines électriques.
