I have a plant polysaccharide which is soluble in D2O. To acquire 13C NMR is it prerequisite for me to add a drop of CDCl3 or d6-DMSO to the sample?

It is a heteropolysaccharide that I have. In spite of high concentration and purity it's been difficult getting a good C13 spectra. Any suggestions will help.
