This is an all-inclusive site in terms of information about HPLC. What may be most useful to students, faculty and early practitioners of HPLC are “New Academia Area” and “Life Science Solutions […]
Although this website by the U.S. Geological Survey (USGS) does not contain analytical data or methods per se, it is one that contains a complete compendium of links to material on environmental […]
This website provides an introduction to linear sweep and cyclic voltammetry. The shape of the current-voltage curve for these techniques is explained with illustrations of the concentration profiles from the electrode surface […]
Measurement science used to characterize environmentally important species is a central aspect of this textbook and accompanying lecture support/PowerPoint presentations. In addition to discussing the hows and whys of measurement, the discussion […]
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. […]
This is a pdf version of an official EPA method for the analysis of cyanide. It discusses a variety of quality control procedures a wide range of controls that must be used […]
If you want to understand atomic spectroscopy, then it helps to have some understanding of the structure of an atom. In this General Chemistry Online eText, the authors give a thorough descriptive […]
US Environmental Protection Agency site that explains GC for those interested in environmental analysis. Assumes some user background in the field. Includes a partial list of EPA Field Methods that utilize GC […]
This is a link within the Waters HPLC Primer site. It contains very useful details regarding the properties of HPLC packing materials and how they impact performance. Since it is part of […]
This experiment demonstrates cyclic voltammetry, surface modification, selectivity, and bioanalysis in assaying catechols in the presence of ascorbic acid. Pre- or post-lab questions are included, along with sample student data and instructor’s […]
This online article describes an inquiry-based experience designed to integrate concepts in water quality and geology for pre-education science students preparing to become teachers at the primary and secondary level. The field […]
