PROBLEM TO BE SOLVED: To provide a solution controller which can accurately and efficiently carry on calibrating work by easily supplying a calibrating solution containing a component at a known concentration. SOLUTION: Short-circuiting pipes 62 and 66 which short-circuit a connecting pipe 53 between closed storage tanks 51 and 52 and a solution storing tank 50 to a pipeline 1 in a component analyzing section 101 are connected to the middle of the pipe 3 through solenoid valves 2, 70, and 68 and a cleaning solvent containing a component at a known concentration is directly supplied to a component analyzing section 101 through the pipes 62 and 66 as a calibrating solution. |
