Split-Flow Thin (SPLITT) Cell Separations Operating under Sink-Float Mode Using Centrifugal and Gravitational Fields
Particles of two
different densities can be continuously and rapidly
separated by employing sink-float phenomenon in split-flow thin (SPLITT)
cells using both centrifugal and gravitational fields. Separation
of a binary mixture of submicron size latex beads differing in densities
is achieved by feeding them as a suspension in a carrier liquid of
intermediate density into a SPLITT cell subject to a centrifugal field.
A steady state condition is rapidly achieved, and two particle types
accumulate at opposing channel walls as they are carried by the laminar
channel flow to two separate outlets. Similarly, micron size particles
of two different densities are separated using a planar channel and
the gravitational field. Equations are developed to predict throughput
in terms of the number fractions of the separated particles determined
by scanning electron microscopy. Experimental results from three SPLITT
cell systems under different field and flow conditions are compared
with theoretical predictions
