Abstract
PURPOSE:To improve the accuracy of measurement by providing an evaporating part for heat pipes near a light source lamp, and quickly conducting the heat of the light source to the outside thereby stabilizing the quantity of irradiation light. CONSTITUTION:Working fluid 11 such as water, ammonia, methanol, ''Dowtherm A '' is put in a metallic pipe 10 of copper, aluminum, stainless steel or the like, and the inside of the pipe is evacuated and sealed, whereby a heat pipe 14 is formed. If the plural heat pipes 14 are put near a light source lamp 6 and an evaporating part 12 is heated, the working fluid 11 deprives of evaporating heat and evaporates. The heat of evaporation is dissipated in a condensing part 13 to the outside of a photometer cover 1. Since the circumferential part of the lamp 6 is effectively cooled without using any fan, the stable quantity of light is emitted. The light transmits through a flow cell 2 sucking up a sample soln. 5, is divided to respective wavelengths by grating 3, are photoelectrically converted by a detector 4, the outputs whereof are recorded in a recorder 16 via an amplifier 15. Thereby, the stable light source is formed by the simple construction, and the accuracy of measurement is improved.
