Vv. Guryanova et al., LIMITATIONS OF GEL-PERMEATION CHROMATOGRA PHY ANALYSIS OF POLYMERS WITH MOLECULAR MASSES HIGHER THAN 10(6), Vysokomolekularnye soedinenia. Seria A, 35(8), 1993, pp. 10001341-10001344
The limitations in gel permeation chromatography (GPC) analysis of pol
ymers with molecular masses (M) higher than (2 - 3) x 10(6) are consid
ered. The limit volumes, concentrations of the injected sample, and th
e eluent flow rates which do not induce the concentration and volume o
verloads during the analysis are determined. The molecular masses of p
olystyrenes (PS) with M > (5 - 7) X 10(6) determined based on small-an
gle light scattering using laser detector after elution were found to
be two to three times lower than initial ones.
