Abstract
The construction of a simple wall-jet detector cell, which can be used either with a solid electrode or with a sessile mercury-drop electrode, is described. The cell consists of two interlocking parts that hold separately the working electrode and the eluent inlet. The detector is used partly immersed in electrolyte solution to give contact with a counter and a reference electrode. Use of the cell is illustrated by determination of permitted synthetic food colouring matters at the 0.1 µg ml–1 level with both electrodes.Keywords
