PURPOSE:To homogenize the mixing ratio of two liquid fed to a joining part by partitioning the inside of a damper in which two kinds of liquid are introduced with an elastic diaphragm and bringing the two kinds of liquid into contact with each other via the diaphragm. CONSTITUTION:Liquids A, B fed to the pipelines 3, 4 from the vessels 1, 2 have different pulsating flows by means of the characteristics of pumps 5, 6. When the liquids A, B are fed into two chambers 7a, 7b which are partitioned by an elastic diaphragm 8 incorporated in a damper 7, the variation of pressure of one hand is immediately transferred to the other hand because the diaphragm 8 is freely moved. Thereby, the pressure variation of the liquid A, B in the outlets 9, 10 of the damper chamber is made to the same phase. Therefore, two liquid flowing into a joining part 11 are fluctuated in the flow rate but introduced into a detector 13 from a discharge port 12 in a specified ratio with the stable mixing ratio. By this mechanism, the output from the detector 13 for flow injection analysis or the like, especially the stability of base line is improved. |
