Craig countercurrent extraction machine applet

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…

Chromatography theory and modes

This site is an introductory lecture in outline form about chromatography. It appears directed toward biochemical separations. The coverage is broad but not deep. Discussions of counter-current separations, gel permeation, and ion exchange are accompanied by some mention of partition, paper, and gas chromatography The website is available here .
