ABSTRACT:
A coulometric flow cell having a defined flow path, and a working electrode in the form of a porous conductive matrix of a selected electro-conductive material in finely divided or powdered form, confined within a segment of the flow path, is described. The cell has particular utility for use with a liquid chromatography separation, and when placed in line upstream of sample injection, will remove selected electroactive components in the carrier fluid, and thereby reduce background level of contaminants reaching the column and eluting from the column. The cell may also be placed in line following sample injection whereby it may be employed to electrochemically modify selected materials in the mobile phase whereby to change their chromatographic characteristics. The cell also may be advantageously employed for direct testing or measuring of a sample solution.
