Abstract

Presesnt of Iast traces of unwanted residual gasese in gas mixture as in environments have posed a eonsiderable  problem in many industries and research establishments (1) .Espacially in applications where the system can combine with residual gases giving the adverse effects. This paper mainly deals with the detection of oxygen as residual gas when it is present in small quantity . Using a new modified instrument basesd on electrical conductivity measurements.
