Current Conductance

A modification in the employment of the direct current method of measuring conductivities is described. The main objective is that pure metallic probe and current carrying electrodes can be used, thus making it possible to investigate the conductivity of solutions such as hydrogen peroxide, aqua regia, etc. This necessitates a choice of electrodes which are inert to such solutions. An electrometer having an infinite resistance so as to avoid any polarization at the probes, in this case the quadrant electrometer, is described in its use as a null instrument. An accuracy as high as or greater than that of the alternating current method could be obtained. Furthermore, this method entails greater equipment economy and simplicity in apparatus required.
