Mono-, Di- and Trisaccharides (2)
RSpak
DC-613 isa column for the analysis of saccharides
by normal phase mode. Under this mode, saccharides are basically eluted in increasing
order of molecular weights. An increase of organic solvent in the eluent delays the elution of saccharides.
For DC-613, it is necessary to do the analysis at 60deg-C for preventing the anomer
separation.
Please compare with the case of Asahipak NH2P-50
