A rapid, reproducible method for investigating the molecular mass distribution of urea formaldehyde resins by size exclusion chromatography has been developed. By using concentrated lithium chloride solution to prepare the sample, materials of high viscosity and high molecular mass can be easily dis

Differential size-exclusion chromatography (SEC) is used to characterize complexes formed between gelatin and two synthetic polyelectrolytes, sodium poly(styrenesulfonate) and sodium poly(2-acrylamido-2-methylpropanesulfonate). The analysis is performed under aqueous, low-salt conditions where maxim
Size exclusion chromatography was used in order to characterize organically bound aluminium in natural water samples. A Superose column was used, with 0.1 M acetate buffer (pH 4.6) as mobile phase. Three detection systems were used; graphite furnace atomic absorption spectrometry, post-column reacti
Superabsorbent polymers are cross-linked poly(acry1ic acid) with some degree of neutralization. These polymers have found extensive use as constituents in personal care products such as sanitary napkins, incontinent devices, and disposable baby diapers that absorb body fluids. Polymer networks are f
