This website offers educators a set of eight classical electroanalytical experiments suitable for use in a quantitative analysis, instrumental analysis, or electrochemistry course. The materials should be useful for advanced undergraduates and beginning graduate students. Experiments include coulometric, conductometric, and potentiometric titrations, stripping analysis, flow injection analysis, and polarography. The experiments are designed around a common…
This experiment is designed for senior undergraduate students in an inorganic chemistry course. Students are asked to synthesize a sonogel-carbon electrode that is modified with a ZrO2 sol-gel and to compare the results to those of an unmodified electrode for the detection of phenol.

This labware module contains directions for seven experiments in analytical electrochemistry. The experiments are designed to illustrate fundamentals of electrode reactions as applied to readily accessible redox reactants. They provide insight to dynamic electrochemistry for scientists at all levels of training. Activation procedures to prepare glassy carbon electrodes are provided in a TechNote.

This lab experiment uses cyclic voltammetry to determine the concentration of acetaminophen (active ingredient of Tylenol) in a children's pain relief elixir and to study the pH dependent mechanism of its oxidation. The experiment includes theory, pre-lab, write-up instructions and reference article.

A discussion of immunoassays in the context of testing for environmental contaminants, including a fairly detailed explanation of how immunoassays are conducted and advantages and limitations in the analysis of environmental problems. There is also a discussion of analytical concerns - interferences, limits of detection, accuracy and precision, calibrating immunoassays, etc.The website is available here…
