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 […]
Means, standard deviation, and deciding if two results are different at some level of statistical significance is the basis for analytical decision making. This module teaches students how to use t-tests, Q-tests, […]
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 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 […]
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. […]
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 […]
When infrared light is absorbed by molecules, it causes them to vibrate. This paper includes computer animations of molecules vibrating. The animations show two simple molecules (sulfur dioxide and carbon dioxide) vibrating […]
