Compact, transportable, and multipurpose highhyphen;pressure unit for UVndash;VIS spectroscopic measurements at pressures up to 200 MPa

摘要

The construction of a compact, transportable, and multipurpose highhyphen;pressure unit consisting of a pressure generating system and a fourhyphen;window optical UVndash;VIS highhyphen;pressure cell for spectroscopic measurements at pressures up to 200 MPa is described. The pressure generating system can be operated with a wide range of liquids suitable as pressurizing medium. The optical cell can be used for spectroscopic and kinetic (flash photolysis and laser inducedThyphen;jump) measurements.
