An Inexpensive Device for Capillary Electrophoresis with Fluorescence Detection
Anderson, Greg; Thompson, Jonathan E.; Shurrush, Khriesto
Journal of Chemical Education, v83 n11 p1677-1680 Nov 2006
We describe an inexpensive device for performing capillary electrophoresis (CE) separations with fluorescence detection. As a demonstration of the device's utility we have determined the mass of riboflavin in a commercially available dietary supplement. The device allows for separation of riboflavin in [asymptotically equivalent to] 100 s with a mass limit of detection of [asymptotically equivalent to] 10 fmol. The device may be of particular interest to faculty at smaller chemistry departments that do not currently possess a CE instrument. While of limited utility, the device we describe could be used to introduce students to capillary electrophoresis despite the obstacle of limited funding. (Contains 2 figures.)
