Which article are you evaluating?
Chromatography

Why you have chosen this article to evaluate?
I chose this article because chromatography has had relevant applications in this course and in our laboratory experiments, and because chromatography refers to a number of ways one can separate compounds by some differential characteristics. My preliminary impression of it was that it had many sections pertaining to different types of chromatography and its practical applications.

 * The lead section gives a good breakdown of chromatography as a whole. In this section, I would broadly mention some of the characteristics of compounds that can be used to separate them by chromatography, such as size, charge, affinity.
 * The section for chromatography terms is helpful in that many of the vocabulary used to describe chromatography can be easily confused, such as eluent/eluate/eluite - if these were used in the article without defining them in this section, this would certainly cause more confusion.
 * When initially scrolling through the article, I was distracted by the large image of column chromatography, which appears to be the only media on the page that extends to obstruct the sidebar to the right. It's a helpful graphic, but I would switch it out for a more concise image or resize the existing image to be less distracting.
 * The following sections for each variety of chromatography go into detail about what properties of molecules each respective technique can separate by. It would be helpful to mention whether each chromatographic technique is restricted to/best applied to specific molecules, or if molecules are limited by which techniques can be use to separate them. For example, if proteins may be separated by their size, charge, solubility, or affinity for a specific compound, which chromatographic technique you may use in each instance.
 * This article was found on the Chemistry WikiProject, and has had numerous revisions, but the Talk Page appears fairly inactive.
