Abstract :
Various methods of determining electrode mass loading are presented, and measurements of mass loading using several of these techniques are compared. Variations between the values of mass loading obtained by the different techniques are discussed and a model is proposed to explain the differences. A simple first approximation to the effects of lateral boundedness which provides qualitative insights as to the cause of the variations is presented
