High-performance liquid chromatography diffusion rate

The performance of several column packings has been assessed and it has been stressed that low eluent flow rates are necessary for high performance separation. The effects of water contamination in eluents has been studied by Berek et a/. " highlighting the need for rigorou dried systems. Phase equilibria studies in polymer-polymer-solvent systems have proved feasible using a dual detection system and could be extended in the future. Other applications are concerned with copolymer analysis, polydispersity, oligomers, and melamine-formaldehyde and urea— and phenol-formaldehyde resins. New techniques, recycle liquid SEC, phase-distribution chromatography, and the measurement of diffusion coefficients from GPC have been described. [Pg.249]
