摘　　要：设计和研制了一种用于溶液样品光学特性原位检测的高压光学样品池成套系统,组件包括手动泵、增压器和高压样品池。其中样品池开有3处光学窗口,以水为传压介质,设计的最高使用压力为600MPa。当用JGS1石英作窗口时,密封和保压效果良好;由于受到石英材质强度的限制,使用压力应控制在300MPa以下。为检验该系统在高压原位检测方面应用的可行性,进行了色氨酸高压荧光光谱的采集。An instrument design of a high-pressure optical cell system for in situ detection of aqueous samples was reported, including a manual pump, a pressure multiplier, and a high-pressure cell. The cell with three optical windows can be used within a pressure range of up to 600 MPa, using water as the pressure transmitting medium. When JGS1 quartz windows were employed, the safe pressure was around 300 MPa. The hermetic sealing effect of quartz was so good that the pressure was hold very well during experiments. In order to demonstrate the functioning of the system,the fluorescence spec tra of tryptophane was determined at different pressures.
