On that account we designed and constructed a miniaturized capillary electrophoresis system which can achieve fast separations due to short capillary length and high electric ﬁeld strength. An integrated and exchangeable autosampler unit which can be loaded with 19 samples at once allowed high-throughput measurements with small sample volumes down to 30 mm . The design of the device enables the implementation of various detectors. The aim of this work was the analytical characterization of this device in combination with mass spectrometry, Keywords Capillary zone electrophoresis Amino acids amperometric and capacitively coupled contactless con- Mass spectrometry Amperometric detection ductivity detection. Hydrodynamic and electrokinetic Contactless conductivity detection injections were carried out with different injection parameters.
