Separation Science

Separation Science

A series of collaborative learning activities and accompanying text that develop the field of separation science, with a particular emphasis on chromatographic separations, is provided. These activities are intended to be done in class by students working in groups, but can be modified for use as out-of-class exercises. Learning objectives, an instructor’s manual, and out-of-class problems…

Introduction to Chromatography

Introduction This learning module provides an interactive introduction to chromatography with an emphasis on understanding basic chromatographic terms and measurements, and on understanding the factors that affect the quality of a separation. The treatment is independent of the form of chromatography and, although data from GC and HPLC experiments are used to illustrate topics presented in…

Chromatographic Peak Broadening

Students explore the contributions to broadening of chromatographic peaks including longitudinal diffusion, eddy diffusion, and liquid and stationary phase mass transport. There is an associated text that explains the answers to the questions on the worksheet.
