PURPOSE:To eliminate the need for complicate calculation by adding a function which calculates a gradient profile when a user inputs a time plan regarding a solvent mixing ratio, and calculates and displays the consumption of each solvent together with the gradient profile. CONSTITUTION:This describes the use of three kinds of solvents. Those three kinds of solvents 1a, 1b, and 1c are put in storage tanks 2a, 2b, and 2c respectively and sucked by feed liquid pumps 4a, 4b, and 4c. The respective solvents 1a-1c supplied by the pumps 4a-4c are sent to a mixer 5 through flow rate regulators 3a, 3b, and 3c, and mixed. Their mixing ratio is controlled through the regulators 3 controlled by a system controller 9. An analytic sample is injected into the solvent by an automatic sample injecting device 8 and the solvent is recovered by a solvent recovering device 12 through a column oven 10 and a detector 11. Then, items necessary for this analysis are displayed on a cathode- ray tube display device 13. |
