Recent studies describe the use of cyclic voltammetry in conjunction with controlled-potential coulometry to study the oxidative reaction mechanisms of benzofuran derivatives [115] and bamipine hydrochloride [116]. The use of fast-scan cyclic voltammetry and linear sweep voltammetry to study the reduction kinetic and thermodynamic parameters of cefazolin and cefmetazole has also been described [117]. Determinations of vitamins have been studied with voltammetric techniques, such as differential pulse voltammetry for vitamin D3 with a rotating glassy carbon electrode [118,119], and cyclic voltammetry and square-wave adsorptive stripping voltammetry for vitamin K3 (menadione) [120].

Stripping voltammetry has also been applied to the quantitation of the drug in formulations. A sensitive and precise method using square-wave adsorptive stripping voltammetry has been developed for the determination of sulpha-quinoxaline in veterinary formulations [157]. The differential pulse adsorptive stripping voltammetric determination of midazolam in injectable formulations as a method for quality control has been demonstrated [158]. [Pg.795]

Microfluidic chip devices are also shown to be attractive platforms for performing microscale voltammetric analysis and for integrating voltammetric procedures (linear-sweep, square-wave and adsorptive-stripping voltammetry) with on-chip chemical reactions and fluid manipulations [97]. [Pg.841]

The electrochemical behavior of Cd-oxine complexes was analyzed by square-wave stripping voltammetry [80] from the mechanistic point of view, applying the theoretical model developed previously [81-83]. Influence of ligand and reactant adsorption, and the ligand concentration on the Cd-oxine electroreduction were also examined [84] using SWV. Typical curves recorded and calculated for several Egw are shown in Fig. 5. [Pg.776]

Application of adsorptive stripping analysis to the determination of nucleic acids at mercury electrodes has also been reported [195]. Tomschik etal. [196] have studied reduction and oxidation of peptide nucleic acid and DNA at mercury and carbon electrodes. The authors have utilized cyclic and square-wave voltammetries to study reduction and oxidation signals of single-stranded peptide nucleic acid and DNA decamers and pentadecamers. [Pg.984]

Electrochemical measurements have been developed by using different electrochemical techniques (differential pulse voltammetry (DPV), cyclic voltametry (CV), potentiometric stripping analysis (PSA), square wave voltammetry (SWV), adsorptive stripping transfer voltammetry (ASTV), etc.). The abbreviations given in covalent attachment of DNA onto different transducers are water soluble carbodimide l-(3-dimethyaminopropyl)-3-ethyl-carbodimide (EDC), IV-hydroxysuccimide (NHS), mercaptohexanol (MCH), aminoethanethiol (AET), mercaptosilane (MSi), and N-cyclohexyl-lV -[2-(N-methylmorpholino)-ethyl]carbodimide-4-tolune sulfonate (CDS).
