Patent

CA 2525230

A liquid sample is prepared at a preparation site and then processed, e.g. in an HPLC column. Fluid supplies (20A, 20B) supply working fluids at flow rates measured by flow meters (24A, 24B). Rotary valve (12) has six external ports (12A-12F). The outputs of the working fluids are combined and delivered to port (12A). Port (12B) is connected via loading conduit (181) to ~LC column (18), the output of which flows to detector (26). A controller (22) controls the operation of valve (12) and supplies (20A, 20B), using input from the flow meters.

Selon l'invention, un échantillon liquide est préparé dans un site de préparation puis traité, notamment dans une colonne HPLC. L'échantillon est préparé et transporté jusqu'au dispositif à une vitesse d'écoulement qui est sensiblement inférieure à la vitesse d'écoulement dans le dispositif. Ces différences de vitesses d'écoulement sont, de préférence, dues à une alimentation en fluide de travail à vitesse variable qui entraîne l'échantillon à partir du site de préparation et à travers le dispositif.
