A new fiber-optic high-pressure cell for time-resolved absorbance and fluorescence measurements in near- and supercritical solvents is presented. It consists entirely of commercial components, thus facilitating ease of construction and maintenance and facilitating component exchange to incorporate materials that can withstand a broad range of pressures and temperatures. The adaptability of the cell and the applicability of the pressure-sealing technique to a variety of emission and fast kinetic measurements are discussed.
