Liquid chromatographic flow cell

Abstract

A liquid chromatographic flow cell for measuring constituents of a specimen solution, comprising at least two electrodes, each having a first through hole, an insulating member having a second through hole and so disposed as to electrically insulate the electrodes from each other, a first and a second supporting members for clamping therebetween the electrodes and the insulating member in such a way that the first and the second through holes are coaxially aligned so as to define a first passage of the specimen solution and having, respectively, a second passage and a third passage of the specimen solution which communicate with the first passage, a first light guiding member for guiding a light for measuring an absorbance of the specimen solution into the second passage defined in the first supporting member, and a second light guiding member for guiding the light transmitted through the third passage defined in the second supporting member to means for measuring an absorbance of the specimen solution. Both the electric conductivity and absorbance of the constituents of a specimen solution dissolved from a column can be measured simultaneously and continuously within the same cell.
