ABSTRACT:
A flow cell is disclosed for collecting and concentrating a sample dispersed in a flowing medium. The collected sample can be selectively manipulated within the cell by the use of one or more traveling wave grids. The cells are particularly useful as bio-enrichment devices and can be utilized upstream of conventional analytical or detection instruments.
