Bv. Huff et Gl. Mcintire, DETERMINATION OF THE ELECTROPHORETIC MOBILITY OF POLYSTYRENE PARTICLES BY CAPILLARY ELECTROPHORESIS, The Journal of microcolumn separations, 6(6), 1994, pp. 591-594
Capillary electrophoresis (CE) can be used to determine the electropho
retic mobilities of polystyrene particles from the migration times of
these particles assuming that (1) the particles do not interact with t
he capillary wall, (2) the particles can be detected, and (3) the coll
oidal suspension of particles is physically stable over the time cours
e of the CE experiment (i.e., > 5 min). CE offers advantages of small
sample size, automation, and ease of analysis. CE determined mobility
data are used to qualitatively assess the adsorption of polymeric surf
actants onto polystyrene particles.
