Abstract

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.

より測定精度および感度を上げられない欠点があった。Generally, in order to mix two liquids stably, it is necessary for each of these two liquids to have completely pulsation-free flow, but this is practically impossible to achieve in 1! It is IIl. For this reason, when two liquids are combined and mixed in FIA, the mixing ratio fluctuates due to the pulsating flow of each flow path system, and this disturbs the baseline of the flow of the two liquids, making it difficult to obtain accurate analysis results. I didn't get nine. In order to solve this problem, the conventional method was to keep the mixing ratio constant by inserting dampers into each of the nine channels and homogenizing the flow rate or pressure independently for both channels, but this method It is not possible to completely eliminate pulsating flow,
Fluctuations in the mixing ratio due to residual pulsation that could not be removed were unavoidable. For this reason, there was a drawback that measurement accuracy and sensitivity could not be improved due to fluctuations in the baseline of the detection output.

The liquid is sent to the damper 7 via the pipes 3 and 4 by the pump 5.6. The interior of this damper 7 is divided into two chambers 7a and 7b by a freely movable diaphragm 8, and the two types of liquids A and B are sent to the respective chambers 7a and 7b and come into contact with each other through the diaphragm 8. ing. These two liquids A and B are separated into two chambers 7a and 7b within the damper 7.
It is discharged from an outlet 9°lO provided at the lower part of each of the two parts, and is introduced into a detection amount 13 from an outlet 12 via a confluence part 11.

At this point, the liquids A and B sent from the containers 1.2 to the pipes 3 and 4 by the pumps 5 and 6 have different pulsating flows depending on the characteristics of the pumps 5 and 6, respectively. When these liquids A and B are sent to two chambers 7a and 7b partitioned by a diaphragm 8 in the damper 7, the diaphragm 8 moves freely, so pressure fluctuations in one are immediately transmitted to the other, and the damper chamber outlet The pressure fluctuations of liquids A and B at points 9 and 10 are in the same phase. Therefore, the confluence part 1
There is a fluctuation in the flow rate of the two liquids flowing into the first part! The ratio of the substances is constant, and the mixture flows out from the outlet 12 and is introduced into the detector 13 with a stable mixing ratio.
