Ls. Litvinova, PRACTICAL ASPECTS OF THE ADSORPTION CHROMATOGRAPHY OF SYNTHETIC-POLYMERS, JPC. Journal of planar chromatography, modern TLC, 11(2), 1998, pp. 114-118
This work considers some of the features of the chromatographic behavi
or of macromolecules. It discusses the limitations of chromatography f
or such substances and the neu separation mechanisms which result from
the macromolecules' complex structures. A method of mobile phase sele
ction for adsorption thin-laver chromatography is proposed for separat
ion of homopolymers according to molecular weight (determination of ph
ysical dispersity). Mobile phases far separation of poly(ethylene oxid
e) and polyvinylpyrrolidone according to molecular weight are given as
examples.
