Electrochemical analyzer - for quantities of ionized or gaseous substances dissolved in liquid

摘要

Esp. for analysis of HCl and Cl2 content of a gaseous mixture which is absorbed in water, voltages corresp. to the interwave reduction level of each component are applied alternately and automatically, in a fixed cycle to the cell terminals by a programme unit will relays a regulated dc dource and a turn track pen recorder. The voltages are 2.5V for HCl and 0.8V for Cl2 and are derived from a potential divider chain across the supply. The relays short circuit the cell terminals and the inputs to the recorder during each change over to equalise the electrode potentials.
