[edit]For those who are interested and have time: the german wikipedia has a good page about the Van Deemster equation.
The Van Deemter equation is highly used in HPLC to improve effiicency. I'll try to clean up the article, I think there's something on this at my website [1] -PaulHurleyuk 10:05, 5 May 2006 (UTC)
The first sentence is very confusing. There was no mention of HETP, which is what van Deemter originally used. Also, the C term in the equation I've always known as representing mass transfer kinetics. Katze015 17:21, 25 July 2006 (UTC)
Another technical thing I thought of, I dont think that van is capitalized in van Deemter. I may be wrong. Katze015 18:40, 26 July 2006 (UTC)
- The term "flow rate" is incorrect. It should be "linear velocity". changed on 25 Oct 2007 --Xenofonos 19:00, 25 October 2007 (UTC)
This whole article is actually quite unreadable. What should be the most important section of an article about an equation--you know, the section describing the equation--has no introduction, does not define the primary variable on the left side, and does not really explain what any of the other variables are. Example: "C = mass transfer kinetics". How can a variable equal "kinetics"? This is quite meaningless. -24.13.168.97 (talk) 06:02, 27 May 2012 (UTC)
van Deemter plot figure is wrong
[edit]The way this article depicts the van Deemter figure is wrong. It confuses the longitudinal diffusion piece (B/u) with the resulting sum of all the terms. As soon as I figure out how to edit stuff in this language I'll try to fix that.

Alex is correct, though I can't edit the figure either. The actual sum of all terms is not shown on the graph, but would be higher than all of three lines (since it is their sum). 99.231.189.25 (talk) 03:09, 25 October 2009 (UTC)
