Abstract

Analysis of a liquid, e.g. determination of chlorine in a water supply, is carried out using an electrochemical method in which a sensing element, in which an electrode (1) is carried on a substrate (2), is subjected to mechanical pulses by a pulsing means (42). The electrode or electrodes may be of the microband type in which the working surface of the electrode is a thin line, the width of which is a microdimension. The method can also be used for determination of non-electroactive species, and of acidity or other physical properties of a solution.
