ABSTRACT:
A separation element is provided for use in a chromatographic analysis system for the separation of a mixture using a stationary phase and a mobile phase. The separation element comprises a fluid transmissive fiber rod comprising a plurality of fibers entangled to provide a tortuous path through which a mobile phase may flow as part of a separation process. The plurality of fibers provides a stationary phase for the separation process.
