Abstract
An electrochemical gas sensor is described for detecting a gas constituent, for example hydrazine in a gas ambient incorporating an electrochemical cell including a reference electrode, counter electrode and sensing electrode spaced apart and with an electrolyte in contact with each electrode and comprising n-methyl-2-pyrrolidone and a salt soluble therein, for example tetraalkyl ammonium salt. The invention overcomes the problem of specificity, service life and operating temperature range associated with aqueous electrochemical gas sensors.
