Kinetic Capillary Electrophoresis is a family of methods for studying binding of biopolymers, measuring rate constants, binding constants, and in some cases providing mechanistic details. This annimation illustrates several kinetic CE modes and their effect on the complex formation and dissociation.

This Quick Time movie illustrates and describes to operation of a Czerny-Turner monochromator. The slits, mirrors, grating and grating scan are described in the production of a specific wavelength at the outlet slit. The movie is a companion to the double beam spectrometer animation.The website is available here .
This site produced by the Dolan DNA Learning Center of the Cold Springs Harbor Laboratory contains a number of high quality animations that explain processes important in bioanalytical chemistry. For example, one animation illustrates the process of Sanger sequencing and another explains what Gene Chips are and how they work. PCR, gel electrophoresis, cloning, model organisms…
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 in different modes. In the examples, animated movies show the fundamental vibrational modes of sulfur dioxide and carbon dioxide. Similarly, animations show the composite…
This site is devoted to statistical tests and demonstrations of their use and was created with the support of the National Science Foundation. One section is a complete reference guide - the online statistics textbook, with detailed descriptions of all things statistical. The second, and most fun section, is simulations/demonstrations section where nearly twenty statistical tests…
This site provides a useful applet that demonstrates countercurrent extraction. The explanation of the method is short, but good. The level is appropriate for undergraduate students. The Applet itself is well designed and provides a useful exercise for students around which homework or small-group waork could be developed. The use of color is particularly helpful. The…
This animation site deals specifically with diode array detection for liquid chromatography. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief…
This site offers Java-based applets as organized in 4 categories: analytical and general chemistry, instrumental chemical analysis, instrumentation/signal processing, data analysis/chemometrics. Each applet includes a short introduction followed by a user controlled input of experimental conditions, such as seen for diffusion in electrochemistry.The website is available here .
This is an animated gif that illustrates how scanning tunneling microscopy (STM) works. As such it is valuable to students and faculty interested in learning about this important surface analysis technique.
