<p>PURPOSE:To improve timewise resolution and to make the volume compact by a constitution wherein a total reflecting body has a tubular shape and a specimen flows through the central hole of said body. CONSTITUTION:A total reflecting body 1 has a round rod shape. A central hole 1a is formed along the central line. The outer surface is made to be a mirror reflecting surface by metal plating. Both ends are finished as conical surfaces. The material of the body comprises a material such as Ge having transparency in an infrared region and high refractive index. The inner surface of the central hole 1a is smoothly finished to the degree so that the smooth reflecting surface is provided for the infrared rays. Flowing pipes of specimen liquid are connected to the opening at both ends of the central hole 31a. The pipes are fixed with pushing metal fixtures. Measuring light is orthogonally inputted into the reflecting body 1 through one conical surface of the reflecting body 1 as shown with arrow lines in the Figure. Reflection is repeated between reflecting mirror surface 1b at the outer surface of the body and the inner surface of the central hole 1a. Then the light is outputted through the other conical surface. Since the specimen is made to flow in the reflecting body, the volume of the cell can be made small in comparison with a device wherein the specimen is made to flow along the outside of a cell.</p> |
