LIQUID CHROMATOGRAPHY PUMPING SYSTEM WITH COMPENSATION MEANS FOR LIQUID COMPRESSIBILITY Abstract of Disclosure In a liquid chromatography system including a chromatographic column, a reservoir for a slightly compressible liquid mobile phase, piston means cooperating with the reservoir for pumping the liquid phase through the chromatographic column, and means for displacing the piston at a pre-selected velocity, an improvement is disclosed enabling maintenance of a constant flow in the presence flow resistance changes at the chromatographic column. Such resistance changes may arise, for example, in cosequence of viscosity changes occurring in the liquid phase during the course of gradient elution operation. According to the improvement, pressure control means are provided in the flow path between the reservoir and column, the said means being adapted for maintaining a substantially constant pressure at the reservoir. In consequence flow rate changes arising from expansion or contraction of the liquid phase in consequence of compressibility, are precluded.
