Summary
Capillary electrophoresis (CE), especially free-zone CE, offers a relatively simple separation with moderate selectivity based on the mobility of ions in solution. Laser-induced fluorescence (LIF) detection, an extremely sensitive technique, can be coupled with a variety of separation conditions to achieve sensitive and quantitative results. When these techniques are combined, CE/LIF provides the sensitivity and increased selectivity that makes trace level environmental analysis of fluorescent compounds possible at or below levels typical for gas chromatography (GC)/mass spectrometry (MS). We offer a panoramic review of the role of these tools in solving environmental and related analytical problems before providing a detailed experimental protocol.
