PURPOSE:To obtain a measured value which is high in precision at any time, by using a detector equipped with a detection cell which has a moving cell made of a light-transmissive substance in it. CONSTITUTION:A tank 25 is connected to intake IN and a sample is supplied. Then, electricity is fed to open solenoid valve 2 and the sample enters a tube body 10 by way of filter 1, passage 3 and solenoid 4 and flows out from outlet OUT via solenoid valve 18. Moving cell 12 is pressed up by the sample and when its reverse surface is pressed against O ring 16, the flow of the sample stops. At this time, the liquid in a detection cell gets stationary under the preset pressure of pressure regulator 23. The pressure regulator 23 applies static pressure into the detection cell to eliminate influences of air bubbles, etc. of the liquid in the detection cell. |
