摘要：

A versatile spectroscopic reaction monitoring system for high-pressure liquids and supercritical fluids is described. The cell is designed to be attached to a charge-coupled device array ultraviolet-visible spectrometer via fiber optics, and has been shown to be capable of monitoring high speed reactions and rate of dissolution of a variety of compounds. The design is simple, inexpensive, rugged, and self-aligning. The cell has been tested up to 300 atm and 100 degrees C without failure. (C) 1999 American Institute of Physics.
