• There are at least two different methods used to perform the column chromatography described here. One involves adding the separable material as a solid pre-prepared on silica gel and then topping this layer with sand, the other involves drawing the separable material as a liquid into a sand layer. The article is easier to understand the way it was before I edited it, however it was misinforming. If nothing is said then I will come back and rewrite it to include both techniques, but this will likely make it more difficult to understand... Also the photo is a cool historic image, but the columns don't have resevoirs on them, the solid phase is right to the top, this is something a little different than described in the article.

The article is indeed in need of retooling. As mentioned, only one method is described (no mention of different packing and loading methods). Also the introductory section gets into rather specific information that might be better suited for a "techniques" section. Bottledmark 02:40, 6 November 2007 (UTC)Reply

• no link between Column chromatography and HPLC try google on Column chromatography
• if your really have to disambiguate start column chromatography (disambiguation) page
• a move action destroys the history of the article
• when editors move an article they should take care of broken links
• the new Preparative chromatography article header does not reflect content (not about prep. TLC or many other prep. techniques)
• external link (reference or sources) was provided but not replicated in second move.
• article name should be in bold
• prep article should link back to diambiguation page

V8rik has reinstated the old version of Column chromatography, I have made the new Preparative chromatography article a redirect to Chromatography. Several chromatographic techniques (e.g. HPLC, TLC) can be used on a preparative scale. (Prevously I had accidentally reinstated the poor version of Column chromatography because I was editing the old version while V8rik made his changes.) Cacycle 19:33, 24 July 2005 (UTC)Reply

The sample experiment in the "Systems" section is, at the least, unencyclopædic. Bottledmark (talk) 03:36, 31 January 2008 (UTC)Reply

Hey Overall good job on your article! Nice images! The only thing I noticed that really needs to be fixed is that you have an image insert that isn't showing up since its still a .png format. Other than that it looks good!
