Abstract
The study of biological samples (human/animal tissues, body fluids including blood, urine etc), within the health service, water industry, metallurgy, education, food industry, agriculture, etc., requires simple, precise, sufficiently highly sensitive methods. From this point of view, electrochemical methods, especially voltammetry and potentiometric stripping analysis (PSA), or electrochemical detection used in separation methods, are very well suited.
The applications for these methods are wide ranging however these techniques are especially advantageous due to their possibility to be utilized in analysis of trace elements, their complexes, various inorganic and organic compounds in aqueous as well as nonaqueous systems. A high sensitivity and/or improvement in the signal-to-noise ratio can be attained by electrochemical preconcentration of the analyte and by application of non-stationary measuring techniques in voltammetry.
Computer control of these measurements enables complete automation of the
