Abstract
A thermophoretic filter cell for the filtering of particles from a liquid is constructed in a particular manner so that the liquid introduced into the filter acts as the heat sink. The cell is designed so that the thermophoretic velocity of the particles in the liquid equals or exceeds the velocity (flow rate per unit area) at which the liquid is passing through the filter.
