PROBLEM TO BE SOLVED: To solve the problems wherein, when bubbles are mingled into a fluid sample and the bubbles enter a measuring channel, accurate measurement becomes impossible because a beam is scattered by the bubbles, in a flow cell for the fluid sample used for a purpose for measuring quantitatively and continuously various components in the fluid sample or the like, in light measurement by a polarimeter, a spectrophotometer or the like. SOLUTION: A constitution is adopted, wherein the measuring channel is arranged vertically, and the fluid sample is circulated from the downside to the upside. Hereby, since the bubbles flow smoothly without stopping in the measuring channel because of its property of flowing upward in the liquid, the bubbles are prevented from staying in the measuring channel. Consequently, maintenance or replacement of the flow cell for the fluid sample after dismantling it from a device is not required. COPYRIGHT: (C)2008,JPO&INPIT
