Abstract

PURPOSE: To heighten the precision of the composition of solvent and prevent the shift of the base line in order to perform the gradual elution method by providing a liquid feed device for feeding the mixed solvent by making non-pulsating current to a predetermined column.
CONSTITUTION: The switching controlled select valves 3, 4, by which, the the solvent flowing into and mixed at the mixing chamber 5 at a predetermined mixing ratio from the solvent reservoir 1, 2 are fed to the column. In this instance, there is a liquid feed device having provided a reciprocating pump 22 complimentarily driven so as to make the total discharged flow rate non-pulsating current, a reciprocating pump 27 complimentarily driven with the liquid feed portion 6 for feeding the mixed solvent to the analysis column 9, a single motor 31, complimentarily driving the pumps 22, 27 so as to make the total flow rate of the liquid feed portion 7 for feeding the mixed solvent to the reference column 10 and both the liquid feed portions absorbing from the mixing chamber 5 non-pulsating current. As a result of this, the precision of the solvent composition is heightened and the gradual elution which prevents the shift of the base line can be performed.
