Combination of Group-Selective Fluorescence Labeling with GPC

Combination of Group-Selective Fluorescence Labeling with GPC 

From the integrated signals of the RI detector, which is concentration-sensitive, and the fluorescence detector, which is functional group-sensitive, the total amount of carbonyl or carboxyl groups can be calculated. 

In cellulose chemistry, the term degree of substitution (DS) usually denotes the number of substituted OH groups per anhydroglucose unit with 

Carbonyl or carboxyl group profiles can also be evaluated numerically. This way, the amount of functionalities in preselected regions of the MWD are compared, provided that the samples have similar molecular weights. Certain characteristics of the cellulose state of oxidation or the distribution of 

Through combination of MWD analysis and functional group analysis it also became possible to examine how functional groups in certain regions of the
