Description (résumé)

This video is part of a series of 19 videos for technical gestures in chemistry (with French subtitles). During a chemical reaction, after extraction, you obtain a reaction crude which requires purification to isolate your targeted product. The reaction crude can contain by-products, unreacted starting material, and even impurities that need to be separated from your product that could be used in a later step. Among the purification methods, we can use the chromatographic column.
