PURPOSE:To prepare a mixed liquid with a desired concn., by a method wherein a pressurized stock liquid and a dilutent are flowed into a first definite ratio mixer to prepare a mixed liquid and the pressurized stock liquid is flowed into a second definite ratio mixer along with the mixed liquid prepared by the first mixer as the diluent. CONSTITUTION:In a mixing method using a definite ratio mixer keeping a definite mixing ratio always, a pressurized stock liquid and a solvent such as water or an org. solvent as a diluent liquid are flowed into a first definite mixer 62 to prepare a mixed liquid. In the next step, the pressurized stock liquid and the mixed liquid prepared by mixer 62 as the diluent are flowed into a second definite ratio mixer 64 to prepare a mixed liquid with a desired concn. That is, because the concn. of the mixed liquid can by raised by flowing the pressurized stock liquid into the definite ratio mixer and the mixed liquid once prepared through the definite ratio mixer is used as the diluent, the concn. of the mixed liquid can be further raised. In addition, mixing concn. can be kept constant and the uniformization of conc. can be easily carried out. |
