Title (EN) THERMAL EXPANSION PUMP FOR PULSE-FREE LIQUID FLOW
(FR) POMPE A EXPANSION THERMIQUE POUR ECOULEMENT DE LIQUIDE SANS IMPULSION
Abstract: front page image
(EN)Pulse-free flow, for instance for capillary chromatography, is provided by a pump comprised of a length of heat transmissive tubing filled with a liquid that undergoes thermal expansion upon heating, in conjunction with a heating device that provides uniform heating of the tubing and its contents at a controlled rate.
(FR)La présente invention concerne un écoulement sans impulsion, par exemple pour chromatographie capillaire, produit par une pompe constituée d'une longueur de tube transmettant la chaleur, remplie d'un liquide présentant une expansion thermique sous l'effet de la chaleur et d'un dispositif de chauffage qui chauffe de manière uniforme le tube et son contenu de façon régulée.
