Abstract

A separation device and a separation method for biomolecular sample material and in particular protein mixtures. For this purpose a separation element 10 for the two-dimensional and preferable electrophoretic separation of components of the sample material is provided in area 30 of a separation plane. According to the invention it is proposed that the separation element 10 has a channel or transfer structure 14 for the locally resolved discharge of separated sample components in a transport direction that is at right angles to the separation plane onto a support surface 16 that is preferably suitable for mass spectroscopic analyses.
