UV detector for liquid chromatography

摘要

A UV detector for liquid chromatography is equipped with a light source; a flow cell having a light entrance side and a light exit side; a first optical system for shining light from the light source into the flow cell so as to form an image roughly at the light exit side of the flow cell or at a position outside the flow cell at a prescribed distance away from the light exit side thereof; a light detector; a second optical system for directing light exiting the flow cell to the light detector; and a truncated cone shaped sample chamber formed in the flow cell along the axial direction thereof, with the base of the truncated cone being positioned at the light entrance side of the flow cell.
