The molar mass and rheological properties of an exopolysaccharide (EPS) from Pediococcus damnosus 2.6 were investigated. The molar mass was determined by asymmetrical flow field-flow fractionation coupled with multiangle light scattering and refractive index detection. The EPS was observed to be a flexible chain polymer with a molar mass value of 4×10 6 gmol −1 . Heating the sample...
The size characterisation of modified celluloses is a necessary, but also complex, task that often requires use of different methods. In this paper, two different size characterisation methods were used to obtain molar mass and size information of three hydroxypropylmethyl cellulose (HPMC) samples in four different solvents. The two methods employed were the combination of flow field-flow fractionation...
