Capillary Electrophoresis

Alternative Energies and Atomic Energy Commission Publishes Research in Capillary Electrophoresis

Published in Health and Medicine Week, March 9th, 2012

2012 MAR 9 -- "The physicochemical properties of three different humic substances (HS) are probed using capillary zone electrophoresis in alkaline carbonate buffers, pH 10. Special attention is drawn to the impact of the electrolyte ionic strength and counter-ion nature, chosen within the alkali-metal series, on HS electrophoretic mobility," scientists in Gif sur Yvette, France report.

"Taylor-Aris dispersion analysis provides insights into the hydrodynamic radius (R-H) distributions of HS. The smallest characterized entities are of nanometric dimensions, showing neither ionic strength- nor alkali-metal-induced aggregation. These results are compared with...
