The advantages of the miniaturization technologies in the analytical sciences can be used to the fullest
extend, namely by generating a small (portable) and fast analysis system. While the detection method in many of the labbased capillary-electrophoresis (CE) system is based on optical methods like laser-induced fluorescence [2,3] which
allows for a very high detection sensitivity up to the detection of single molecules, the instrumental components
necessary for such a detection scheme are normally bulky, expensive and due to the mechanical sensitivity of optical
components, not well suited for portable systems. Furthermore, they often require recalibration or adjustment after
moving the instrument which would be counterproductive for an on-site analysis tool.
