Iodine Generation

Faraday Principle

Relationship between the electrical charge and the mass of the reacted substance follows a strict physical law. The amount of iodine produced is calculated by measuring the total coulombs passed through the generator electrode.

Coulometric Application

Precision of the method allows for the detection of trace water levels in high performance polymers that are sensitive to hydrolysis. This iodine generation occurs within a sealed environment to prevent interference from the oxygen in the room.

Stoichiometric Control

Balanced reactions ensure that one mole of iodine reacts with exactly one mole of water in the presence of sulfur dioxide and a base. Automation of the current flow stops the production of iodine the moment the detector electrode senses that all water has been neutralized.
