Abstract
1531761 Electro-chemical detector EDT SUPPLIES Ltd 30 June 1976 [1 April 1975] 13136/76 Heading G1N An electro-chemical detector comprises a thinlayer flow cell in which a solution line 2 terminates in a fine nozzle 7 located normal to but spaced from a surface of a sensor electrode 3 and a control unit which applies a periodically changing voltage to the sensor electrode, the voltage having a first portion functioning as a detecting potential and a second portion functioning as a cleaning potential. The sensor electrode surface is planar and may be a disc, ring or split ring of, preferably vitreous carbon or of platinum, gold or graphite carbon. The distance between it and the nozzle can be altered. A reference electrode and optionally a counter electrode are provided downstream of the sensor electrode. The voltage is preferably a squarewave of variable amplitude, frequency and mark-space ratio. Measurement is preferably carried out during a small part of the detecting portion, towards the end thereof. The solution determined may be the effluent from a high performance, high-pressure liquid chromatography column. As shown, liquid enters the cell via pipe 2 and is directed via nozzle 7 on to sensor electrode 3. The liquid leaves the cell via outlet 4, contacting tubular counter electrode 6 and reference electrode 5 (via salt-bridge leak 10) on the way. The jetsensor electrode distance is adjustable by moving screw threaded electrode support 9. Control unit 11 is connected to the electrodes and to a recorder 12.
