Mass Transport
Limited Current
The current corresponding to the maximum mass
transfer rate of an ion or molecule to an electrode
surface.
Migration
In an electroanalytical context, the term migration
refers to the movement of ions across a solution under
the influence of an electric field.
Non-Faradaic Current
The portion of the current observed in an
electroanalytical experiment that cannot be
attributed to any redox processes occurring at an
electrode surface.
Overpotential
The overpotential is the difference between the
formal potential of a half reaction and the potential
presently being applied to the working electrode.
Oxidation
Removal of electrons from an ion or molecule.
PCTFE
A chemically inert polymer often used as an insulating
shroud for an electrode. PCTFE is an abbreviation for
polychlorotrifluoroethylene.
PEEK
A chemically inert polymer often used as an insulating
shroud for an electrode. PEEK is an abbreviation for
polyether ether ketone.
PTFE
A chemically inert polymer often used as an insulating
shroud for an electrode. PTFE is an abbreviation for
polytetrafluoroethylene.
Quiescent Solution
A solution in which there is little or no convection.
Redox
An adjective used to describe a molecule, ion, or
process associated with an electrochemical reaction.
Reduction
Addition of electrons to an ion or molecule.
Reference Electrode
A reference electrode has a stable and well-known
thermodynamic potential. The high stability of the
electrode potential is usually reached by employing
a redox system with constant (buffered or saturated)
concentrations of the ions or molecules involved in
the redox half reaction.
