Counter-Flow Gradient Electrofocusing

February 1, 2007
Author(s)
Jonathan G. Shackman, David J. Ross
Counter-flow gradient electrofocusing methods are methods whereby a combination of electrophoresis and a bulk solution counter-flow is used to accumulate or focus analytes at stationary points along a separation column. This review first describes the

Scanning Temperature Gradient Focusing

S J. Hoebel, K M. Balss, Barbara J. Jones, C Malliaris, Matt S. Munson, Wyatt N. Vreeland, David J. Ross
Temperature gradient focusing (TGF) is a recently developed technique for the simultaneous concentration and electrophoretic separation of ionic analytes in microfluidic channels. One drawback to TGF as it has previously been described is the limited peak

Micellar Affinity Gradient Focusing

February 25, 2004
Author(s)
K M. Balss, P B. Howell, David J. Ross
This report describes a novel method for the concentration and separation of neutral and/or hydrophobic analytes based on a combination of the analytes partitioning into a micellar phase and their electrophoretic mobility. This method of simultaneous

Chiral Separations by Temperature Gradient Focusing

February 1, 2004
Author(s)
K M. Balss, Wyatt N. Vreeland, Karen W. Phinney, Michael J. Tarlov, David J. Ross
Temperature gradient focusing (TGF) involves application of a temperature gradient across a microchannel or capillary. With an appropriate buffer, the temperature gradient creates a gradient in both the electric field and the electrophoretic velocity
