CHANNEL UNIT AND MICROPARTICLE ANALYSIS DEVICE
FIG2 is a diagram illustrating an experimental system to analyze flow rate fluctuation that occurs in a case of pressure liquid feeding
FIG2 illustrates an experimental system to analyze the flow rate fluctuation that occurs in the case of the pressure liquid feeding. A flow rate sensor used in the experimental system was SLS-1500 manufactured by SENSIRION AG. The shortest interval of flow rate sampling was 1 ms. In other words, the flow rate was measured every 1 ms at the shortest.
