GPC UT-800 series, which are packed with large particle size (30 μm) gel, arerecommended for the analysis of macromolecules. The large particle size prevents potential molecularshear degradation of the sample.15Column : UT-806M x 3(Particle size : 30µm)Vo110120 25Column : AT-806MS x 2(Particle size : 12µm)Vo152230Shear degradation20min3540min10Low density polyethyleneSample : Low density polyethylene (LDPE-C)Column : HT-806M x 2(Particle size : 13µm)1Vo10 15 20 25 min152Shear degradation20Sample :1.
