NANSLO Remote Lab Activity: Gas Chromatography
This NANSLO lab activity is self-contained and can be used in second semester general chemistry and survey of chemistry courses. In this activity, a mixture of four volatile organic compounds is used to illustrate separation and shows how experimental conditions can affect separation based on polarity. The lab activity includes background information which defines polarity, electronegativity, polarity of a bond, and intermolecular forces of attraction. It then discusses what chromatography does to compounds and particles. The lab activity includes pre-lab questions and lab exercises.

- Quality Note:
- Curriculum expert in this discipline worked with Discipline Panel of faculty to define learning objectives needed for this lab activity. During development, teleconferences were held to discuss lab activity being developed. Draft activity was posted to listserv for review by Discipline Panel and other faculty in that discipline. Based on feedback, lab activity was modified prior to posting as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
