Abstract

Cet appareil comporte en dérivation d'une part une boucle de circulation des échantillons à aiguille creuse 26 mobile verticalement, d'autre part un circuit de circulation continue d'un solvant. Un orifice latéral de l'aiguille permet l'expulsion de l'échantillon dans ce circuit lorsque l'aiguille est en position haute. Le solvant de ce circuit passe par un passage annulaire qui est voisin dudit orifice lorsque l'aiguille est en position haute. Des joints étanches 70 sont prévus au-dessus et au-dessous de cet orifice, chacun comprenant un manchon 72 en résine compressible serré entre deux bagues 74-92. Application à la chromatographie liquide
