ABSTRACT:
A direct-heating column assembly for chromatography, includes at least one capillary column and at least one element made of electrically conductive material in contact with the capillary column. The element includes a plurality of filaments woven together to form a tubular mesh that uniformly envelops the outer surface of the capillary column both in radial and longitudinal directions.
