Description:
Application
It may be used in determination of molecular weight of hydrolysate using gel permeation chromatography, in a study performed to investigate enzymatic degradation of chitins and partially deacetlylated chitins of squid pen and shrimp shell.
General description
Pullulan Standards are mostly used to determine molecular mass distribution of cellulosic samples. It mainly consists of polymaltotriose units linked together by α-(1→6) linkages.
