PURPOSE: To determine the representative value of the movability and relative amt. of a solute by immediately moving a capillary tube in the direction opposite to the moving direction of the solute after all of solute peaks pass through a detection window to be detected by a detector to match next detection with the beam of the detector. CONSTITUTION: A capillary tube 12 is composed of fused silica and the outer surface thereof is coated with polyimide 22 and a polyimide film is intermittent and pervious to UV rays and four short uncoated segments 23-26 acting as detection windows are left. The movement of a solute is generated in the direction shown by an arrow 27. A system component is arranged in order to detect the solute through a first detection window 23. Immediately after all of solutes pass through said window, the capillary tube is moved in the direction shown by an arrow 28 toward an UV light source 18 and an optical diode detector 19 until the second detection window 24, the light source and an optical diode are matched. The peak passing through the detector 24 is recorded and, thereafter, the capillary tube 12 is again moved in the same direction and the light source and the detector are matched and the capillary tube moves to the third and fourth windows. |
