Electrochemical Sensors and Detectors with Renewable Electrode Surfaces, active area. An increase in the signal is sometimes observed if metals with low overvoltage of hydrogen evolution are deposited or if the electrode surface is increased by corrosion (often observed with carbon electrodes).

Krzysztof Winkler,Emilia Grądzkas more commonly described as “natural products”. These secondary metabolites are usually less polar than the primary metabolites and are obtained by the extraction of plant material with an organic solvent or steam distillation. Separation of the components then being carried out by crystallisation or chromatography.

Applications of High Performance Liquid Chromatography with Electrochemical Detection in Clinical Cn of urinary levels of catecholamine and tryptophan metabolites. Finally, its value for the estimation of urinary oxalic acid is shown. Future developments such as increasing the range of detectable compounds by derivatization are briefly discussed.
