    The portable capillary electrophoresis instrument is automated and features three independent 23 channels with different background electrolytes to allow the concurrent optimized 24 determination of three different categories of charged analytes. The fluidic system is based on 25 a miniature manifold which is based on mechanicallymilled channels for injection of samples 26 and buffers. The planar manifold pattern was designed to minimize the number of electronic 27 valves required for each channel. The system utilizes pneumatic pressurization to transport 28 solutions at the grounded as well as the high voltage side of the separation capillaries. The 29 instrument has a compact design, with all components arranged in a briefcase with dimensions 30 of 45 (w) × 35 (d) × 15 cm (h) and a weight of about 15 kg. It can operate continuously for 8 h 31 in the battery-powered mode if only one electrophoresis channel is in use, or for about 2.5 h in 32 the case of simultaneous employment of all three channels. The different operations, i.e. 33 capillary flushing, rinsing of the interfaces at both capillary ends, sample injection and 34 electrophoretic separation, are activated automatically with a control program featuring a 35 graphical user interface. For demonstration, the system was employed successfully for the 36 concurrent separation of different inorganic cations and anions, organic preservatives, 37 additives and artificial sweeteners in various beverage and food matrices
