Title
(EN) DUAL MODE SAMPLE MANAGER
(FR) GESTIONNAIRE D'ÉCHANTILLONS À DOUBLE MODE
Abstract
(EN)
Described is a dual mode sample manager for a liquid chromatography system. The dual mode sample manager includes a sample needle, a sample loop, a metering pump, a needle seat and first and second valves. Each valve is configurable in two valve states to enable two modes of operation. In one mode, sample acquired and stored in the sample needle is injected into a chromatography system flow and, in the other mode, sample acquired through the sample needle and stored in the sample loop is injected into the chromatography system flow. The automated switching of the sample manager between the two modes of operation avoids the need for maintaining two separate liquid chromatography systems or manual reconfiguration of a chromatography system for users desiring the capability of both modes of operation.

L'invention concerne un gestionnaire d'échantillons à double mode pour un système de chromatographie en phase liquide. Le gestionnaire d'échantillon à double mode comprend une aiguille d'échantillon, une boucle d'échantillon, une pompe de dosage, un siège d'aiguille et des première et seconde vannes. Chaque vanne peut être configurée dans deux états de vanne pour permettre deux modes de fonctionnement. Dans un mode, l'échantillon acquis et stocké dans l'aiguille d'échantillon est injecté dans un écoulement de système de chromatographie et, dans l'autre mode, l'échantillon acquis à travers l'aiguille d'échantillon et stocké dans la boucle d'échantillon est injecté dans l'écoulement de système de chromatographie. La commutation automatisée du gestionnaire d'échantillons entre les deux modes de fonctionnement évite le besoin de maintenir deux systèmes de chromatographie liquide séparés ou une reconfiguration manuelle d'un système de chromatographie pour des utilisateurs souhaitant la capacité des deux modes de fonctionnement.
