Jean Lafitte National Park and Historical Preserve

Barataria Chromatography Project 2010

Thomas Jefferson High School

Gretna, LA

The Advanced Placement Chemistry class collected water and plant samples along the Coquille Trail at three different sites. Photos and videos were taken at the sites using Flip and digital cameras. GPS units were also used to collect information on the locations. At the education facility's lab, hardness of the water samples was determined through titration and the process of chromatography was used to analyze pigments in the plant samples. The students created a blog about the experience and continue to process data in preparation for the quest that will be produced for the park's website.

Chromatography is the collective term for a set of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates the analyte to be measured from other molecules in the mixture based on differential partitioning between the mobile and stationary phases.
