Title (EN) SPIRAL COLUMN FOR DUAL COUNTERCURRENT CHROMATOGRAPHY
(FR) COLONNE HELICOIDALE DESTINEE A UNE CHROMATOGRAPHIE DOUBLE A CONTRE-COURANT
Abstract: front page image
(EN)A plate apparatus for use in dual countercurrent chromatography comprises a disk shaped column support (60) having a spiral groove (62) formed on its surface. Preferably, at least one layer of fluid flow tubing is positioned substantially within the spiral groove (62). In some embodiments, the dual countercurrent chromatography effect is produced by rotating the disk shaped column (60) on a planetary motion device.
(FR)L'invention concerne un appareil sous forme de plaque utilisé dans une chromatographie double à contre-courant qui comprend un support de colonne en forme de disque à rainure hélicoïdale formée sur sa surface. De préférence, au moins une couche de tubage d'écoulement de fluide est positionnée sensiblement à l'intérieur de la rainure hélicoïdale. Dans certains modes de réalisation, l'effet de chromatographie double à contre-courant est produit par rotation de la colonne en forme de disque sur un dispositif à mouvement planétaire.
