Talk:Centrifugation

message: LOL.
So centrifugation uses the centripetal force huh?
Actually, it is centripetal force. Is your logic behind it being centrifugal simply because of its name? It actually uses both centrifugal and centripetal force, but whatever...

===Cleanup badly needed!===
The current state of centrifugation-related articles on Wikipedia is a terrible mess. Most articles are stubs, lack theory or links to theoretical background articles, are restricted to only a certain field, overlap or conflict with other articles, and/or contain information that is incomplete or sometimes even plain wrong. Part of the problem seems to be that centrifugation is used in so many fields (chemistry, physics, biology, medicine, industry), each of which has its own methods, history and terminology...
I've already tried to clean some things up here and there, but a lot more needs to be done. I would propose at least the following changes:
* Merge the centrifuge and centrifugation articles into a single starting point for the subject, and link to the other articles from there. Alternatively they could remain separate but then they should not overlap as they do now. The overlap with the laboratory centrifuge and ultracentrifuge articles should also be be resolved.
* A better overview of the background sedimentation theory is needed. The articles are mostly already there, but should be linked and/or presented in a logical manner. RCF should probably have its own article, or be merged with centrifugal force.
* Separate sedimentation/centrifugation techniques into categories in a proper and more logical manner. For instance, in biology preparative centrifugation techniques come roughly in three categories, differential sedimentation, rate zonal sedimentation and isopycnic sedimentation. Analytical ultracentrifugation techniques are a separate application, and can be separated in measurements of sedimentation coefficient and sedimentation equilibrium.
* The differential centrifugation article needs cleaning up. The part about isopycnic centrifugation should be moved to its appropriate article, and ultracentrifugation should not be a redirect to this article but rather a separate article (or probably be merged with ultracentrifuge. A separate article should be created for rate zonal sedimentation, and then be merged with Sucrose gradient centrifugation (which is a form of this technique).
I'll see if I have some time to make these changes over the coming weeks...

thread_title: Cleanup badly needed!

message: Hi! I proposed a merger of a few flavors/nicknames of differential centrifugation into that article. I started a discussion about that here. Sorry about starting a parallel discussion elsewhere; I just found this. Does my proposal seem reasonable?Vigormaster (talk) 22:40, 29 March 2009 (UTC)
