ABSTRACT:
A detection system for the detection of e.g. chlorine in a gas stream comprises an elongate support (14) which has electrolyte distributed along its length and is provided with a pair of electrodes (18,20), the electrolyte being chemically reactive with the gas to be detected to produce an electric current detectable by the electrodes. The electrolyte may be distributed along the support by capillary action or it may incorporate a viscosity-enchancing agent to allow the electrolyte to remain in place along the length of the support thereby avoiding loss of electrolyte by dripping.
