Charakterizace degradace celulózy v průběhu urychleného stárnutí pomocí GPC-MALS, GPC-DAD a A4F-MALS
No full textIn this work, we compared three methods of analysis of cellulose in paper subjected to accelerated ageing: size exclusion chromatography in combination with multiangle light scattering (SEC-MALS) detection, size exclusion chromatography in combination with diode-array detector and calibration using polystyrene standards (SEC-DAD), and asymmetric flow field–flow fractionation in combination with multiangle light scattering (A4F-MALS). Prior to separation, cellulose sample were derivatized with phenyl isocyanate to CTC and dissolved in tetrahydrofuran.Práce porovnává tři metody analýzy celulózy vystavené urychlenému stárnutí: gelová permeační chromatografie v kombinaci s víceúhlovým rozptylem světla (GPC-MALS), gelovou permeační chromatografii v kombinaci s detektorem diodového pole a kalibrací na polystyrenové standardy (GPC-DAD) a frakcionaci tokem v asymetrickém tokovém poli (A4F-MALS). Před separací byly vzorky derivatizovány fenyl izokyanátem na CTC a rozpuštěny v tetrahydrofuranu
