Abstract
Le système de pompage pour chromatographie en phase liquide est caractérisée par le fait qu'en aval des deux cylindres (0,1) on trouve un second dispositif (11) anti-retour puis un troisième cylindre (2) branché sur un raccord en T(8) dont le piston (15) est également commandé par un système d'entrainement (18), le premier (0) et le troisième (2) pistons fonctionnant en phase et le second (1) en opposition de phase de sorte que le premier (0) et le troisième (2) refoulent linéairement quand le second (1) aspire linéairement et réciproquement.
