Linear sweep voltammetry - linear scan voltammetry... 

Potentiodynamictechniques— are all those techniques in which a time-dependent -> potential is applied to an - electrode and the current response is measured. They form the largest and most important group of techniques used for fundamental electrochemical studies (see -> electrochemistry), -> corrosion studies, and in -> electroanalysis, -+ battery research, etc. See also the following special potentiodynamic techniques - AC voltammetry, - DC voltammetry, -> cyclic voltammetry, - linear scan voltammetry, -> polarography, -> pulse voltammetry, - reverse pulse voltammetry, -> differential pulse voltammetry, -> potentiodynamic electrochemical impedance spectroscopy, Jaradaic rectification voltammetry, - square-wave voltammetry. 

Under optimized conditions, using differential pulse or square-wave voltammetries, linear peak current vs. dopamine concentration plots can be obtained in the 1-200 pM dopamine concentration range in the presence of 0.1 mM ascorbate, with detection limits (S/N= 3) of ca. 0.3 pM.

As it can provide some of the most basic electrochemical information related to the reactivity of the selected analyte (peak potential and peak current) most instruments that perform amperometry can also perform some of the most basic voltammetric techniques. These techniques determine the current as a function of the potential applied to the WE (in a conventional three-electrode cell) and can be performed with relatively simple instrumentation [105,106]. As different signals can be combined in the input ports of the instrument, multiple variations of the technique have been developed including cyclic voltammetry, linear sweep voltammetry, linear sweep stripping voltammetry, stripping voltammetry [107, 108], fast-scan cyclic voltammetry [109], square-wave voltammetry [110],and sinusoidal voltammetry [111]. 

Electroanalytical methods have been extensively applied in sensing and biosensing. Potentiometry, amperometry, cyclic voltammetry, linear voltammetry, differential pulse voltammetry, square-wave voltammetry, and electrochemical impedance spectroscopy (EIS) represent the most-used electrochemical techniques used for biosensor fabrication and detection.

Bioanalytical Systems BAS 100 and BAS lOOA Electrochemical Analyzers, a PAR 174 polarograph and a pulse generator-transient recorder combination were used for performing cyclic voltammetry, linear-sweep voltammetry, and chronocoulometry. Rotating-disc current-potential curves were recorded with a Tacussel model EDI electrode operating at rates of 100 to 2500 rpm. All measurements were made at ambient temperature (21 2 C) in a single-compartment cell employing saturated calomel (SCE) or saturated sodium chloride calomel (SSCE) reference electrodes and platinum discs as counter electrodes.

The electrochemical reduction of Bi - in AlClg-NaCl melts (52-63 mole % AICI3) has been studied by voltammetry, linear sweep voltammetry, and chronopotentiometry at solid electrodes. Torsi and Mamantov found that Bi + is reduced reversibly to Bi" further reduction of Bi+ to Bi is complex and involves intermediate oxidation states which were not characterized electrochemically. Strong adsorption of Bi " at gold and platinum electrodes was observed. As in other systems,the lower oxidation states were found to be more stable at lower temperatures and in more acidic melts.
