Revising the ACS Guidelines for Chemistry Programs in Two-Year Colleges: Exploring Changes and Opportunities  John V. Clevenger, Margaret S. Richards, and Jodi L. Wesemann
A draft of the next edition of the ACS Guidelines for Chemistry Programs in Two-Year Colleges contains guidelines designed to maximize the potential of students, faculty, and programs in two-year colleges; reflect changes in pedagogy, technology, and accountability; facilitate student transfer; and provide a more useful resource for strengthening programs.

Separation Anxiety: An In-Class Game Designed To Help Students Discover Chromatography  Michael J. Samide
An in-class activity, designed on the basis of plate theory, allows students to physically separate coins on the basis of a provided partition coefficient. Students move coins between stationary and mobile phases to establish equilibrium conditions. The goal is to have students understand equilibration as it relates to separation, which can lead into a discussion of more complex topics.

If You Were a Molecule in a Chromatography Column, What Would You See?  John Mattice
To visualize what takes place in a chromatography column, enlarge the molecules to human size and expand the columns to keep the ratio of size of molecule to size of column the same. Using such a model, this article explains how band broadening occurs as a result of resistance to mass transfer, multiple flow paths, and stagnant mobile phase.

Chromatography, Paper (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Chromatography, Paper: this is a resource in the collection "ChemPages Laboratory Resources". Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires small quantities of material. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Principles of Gel Permeation Chromatography  Guilherme Andrade Marson, Bayardo Baptista Torres
Principles of Gel Permeation Chromatography presents the principles of gel permeation chromatography (GPC) for students in introductory undergraduate courses of chemistry and biochemistry. These principles are presented in four sections: Introduction, Real Lab, Virtual Lab, and Microscopic Model. The Introduction and Real Lab sections present a brief view of the basic experimental apparatus typically used in laboratory GPC in order to provide a concrete connection of the real process of separation. The basic elements of column chromatography, emphasizing the stationary and mobile phases, are presented in the Introduction, followed by a sequence of pictures and texts describing major steps in GPC analysis in the Real Lab section. The Virtual Lab section is a simulator. Three samples are available for a virtual GPC experiment: sample 1, containing hemoglobin; sample 2, containing methylene blue; and sample 3, containing both methylene blue and hemoglobin. Each sample undergoes a virtual separation run, which is dynamically represented in three ways in the software: a virtual column, the collected fractions, and a virtual chromatogram. This threefold representation allows the simultaneous view of key aspects of the process to demonstrate the correlation between the experimental procedure and the resulting chromatogram.
