Greener Alternative to Qualitative Analysis for Cations without H2S and Other Sulfur-Containing Compounds Indu Tucker Sidhwani and Sushmita Chowdhury The classic technique for the qualitative analysis of inorganic salts and mixtures relies on highly toxic hydrogen sulfide. Increasing environmental awareness has prompted the development of a green scheme for the detection of cations by spot tests that is simple and fast. Sidhwani, Indu Tucker; Chowdhury, Sushmita. J.

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. Mattice, John. J. Chem.

Capillary Electrophoresis Analysis of Cations in Water Samples. An Experiment for the Introductory Laboratory Christopher J. Pursell, Bert Chandler, and Michelle M. Bushey This experiment can be done in a lab, as a "dry-lab", or as an in-class exercise. Students explore a number of basic separation topics and work with figures of merit for real and meaningful samples. We have adopted a strategy where students encounter various instruments and methods of analyses multiple times throughout the curriculum. The level of sophistication in the exposures increases with the experience level of the students. Through this repeated exposure students will gain a better and fuller understanding of these methods than they would with a single exposure to the technique in the analytical or instrumental laboratory.

An Inexpensive Detector for Gas Chromatography Allan L. Smith, Edward J. Thorne, and Wolfgang Nadler We have developed a low-cost (parts cost approximately $70) detector that can be used in a freshman level class to demonstrate the fundamental principles of gas chromatography (GC). The detector box can be used in a modification of experiments available in the literature which do not enable a quantitative method of analysis. We have used it with success in a freshman class of approximately 450 students in an experiment to separate chlorinated hydrocarbons via GC. Smith, Allan L.; Thorne, Edward J.; Nadler, Wolfgang. J.
