Abstract
We investigate the sedimentation equilibrium of a charge-stabilized colloid
al suspension in the regime of low ionic strength. We analyze the asymptoti
c behaviour of the density profiles on the basis of a simple Poisson-Boltzm
ann theory and show that the effective mass we can deduce from the barometr
ic law corresponds to the actual mass of the colloidal particles, contrary
to previous studies.
