Capillary electrophoresis (CE) is an efficient tool for amino acid (AA) analysis. However, its role can be fully accounted for only by examining the applications on real matrices. Methods must be successfully transferred into working environments for use by non-CE experts before their power can be realized. This transfer of technology is rapidly increasing. In this chapter, some applications to real samples are presented with the precise intent to illustrate the great capabilities of CE to AA analysis in clinical applications.
