11. MEASUREMENT TECHNIQUES
The HM5000 is capable of running 4 different electrochemical voltammetric
analysis techniques; Linear Sweep, Differential Pulse, Square Wave and Cyclic
Voltammetry. The following gives a brief explanation of these techniques.
Linear Sweep
Linear sweep increases the potential from Ebegin to Eend at the scan rate in V/s.
In any given metal analysis, dependent on whether ASV or CSV is employed, the
metal being examined is being either oxidised or reduced at the electrode at its
redox potential. Linear sweep runs slowly and gives time for the reaction to occur,
but the time at the redox potential is limited and the current generated is low.
