Abstract
A fluid interface port in a separation device for separating a sample into different components is provided. The separation device includes an array of separation channels and the fluid interface port comprises an opening formed in the side wall of a separation channel sized and dimensioned to form a virtual wall when the separation channel is filled with a separation medium. The fluid interface port is utilized to introduce a liquid sample into the separation medium. The fluid interface ports formed in the array of separation channels are organized into one or more sample injectors. A cathode reservoir is multiplexed with one or more separation channels. To complete an electrical path, an anode reservoir which is common to some or all separation channels is also provided.
