The Web site, created by Dr. Thomas G. Chasteen at Sam Houston State University, features an abundance of animations and audio narrations about the subjects of electrophoresis, spectroscopy, chromatography, chemiluminescence, and more. Students can learn about many of the gas chromatographic detectors such as the thermal conductivity detector (TCD), the electron capture detector (ECD), and the flame photometric detector (FPD). At the end of the site, a movie illustrates the steps for the process of a single analyte, ionization and fragmentation of the analyte, mass separation of the charged fragments, the passage of these fragments into the detector, and the detection of the charged ions. Visitors can also find a series of questions to test their knowledge. With its many links to information about gas chromatography-related concepts, chemistry students and educators will find this expansive site very helpful.
