(2020-01-01)
The application of highly sensitive pH sensors manufactured in volume at low cost has great commercial interest due to an extensive array of potential applications. Such areas include industrial processing, biotechnology ...
Screen-printed electrochemical-based sensor for taxifolin determination in edible peanut oils
(Elsevier Science, 2020-12)
An electrochemical method for the determination of Taxifolin (Tx) in peanut oil samples using screen-printed electrodes (SPEs) is reported for the first time. The different electroanalytical parameters such as scan rate, ...
Aspects of cathodic stripping voltammetry at the hanging mercury drop electrode and in non-mercury disposable sensors
(Wiley-Blackwell, 2000-10-01)
Cathodic stripping voltammetry (CSV) and accumulation at the hanging mercury drop electrode are reviewed briefly. Proposals in a recent IUPAC technical report are considered. Three recent developments in CSV are discussed: ...
