摘要：
PROBLEM TO BE SOLVED: To provide a cell used for an absorptiometric automatic quantitative analysis method and an apparatus for accurately measuring a concentration of an ultratrace component in a short time. SOLUTION: The optical flow cell has a shell provided with first and second sections. The first section is provided with a light entrance opening. The second section is provided with an image opening. An entrance pipe and an exit pipe are held between the first and second sections. A view field assembly is held between the first and second sections, and includes a reference plate and a fluid communicating groove. The fluid communicating groove communicates a fluid between the entrance pipe and the exit pipe. The reference plate extends from the shell and functions as a repeatable reference point for properly positioning the optical flow cell. COPYRIGHT: (C)2006,JPO&NCIPI
