Abstract
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 spectra of tryptophane was determined at different pressures.
