Abstract
It is shown that steric exclusion chromatography can be used to measure the size distribution of colloidal gold sols. Good separation can be achieved for particles ranging in size from 3.0 to 20 nm using columns containing 25-µm silica particles (pore size 50–100 nm) and with aqueous trisodium citrate (0.001 M) as the eluent. © 1993, American Chemical Society.
