Abstract

Capillary electrophoresis (CE) is a technique well suited for several separation problems in the life sciences. The main advantages are the higher separation efficacy in comparison to chromatographic methods and the smaller sample volume required. However, due to the limited sensitivity of CE, HPLC remains the method most commonly used for the analysis of drugs in biological fluids. For endogenous compounds like DNA, proteins, or small molecules like purines, CE offers clear advantages over conventional methods and, especially for DNA, CE has already been introduced into clinical routine. Some selected applications will be discussed. Clin Chem Lab Med 2003; 41(6): 720–723
