A capillary electrophoresis (CE) method was developed such that colored dye components of various types of fibers could be separated and identified.  Forensic analysis often involves the characterization of fibers found at crime scenes.  One aspect of fiber evidence that can be used to match crime scene evidence to the belongings of suspects is the composition of the dyes in the fibers.  In this work, we studied natural and synthetic fibers.  Using a novel CE method developed in our lab, we were able to extract the dye components directly from the fiber into the capillary for analysis.  Presented herein are results from numerous injection and separation conditions employed to analyze various types of fibers containing several colored dye components. <br/>
