Description (résumé)

This video is part of a series of 19 videos for technical gestures in chemistry (with French subtitles). During a chemical reaction, unwanted molecules can be observed in addition to your product. The reaction crude then requires purification which can be done on a chromatographic column, the preparation of which was presented in a previous video. In this video, we will discover how to use a chromatographic column in order to separate your cited product from a traditional crude.
