DMAc GPC
We promise to support our clients with various organic/inorganic material R&Ds with utmost sincerity.
KOPTRI provides GPC (Gel Permeation Chromatography) service with DMAc (N,N-Dimethylacetamide).
If the polymer does not dissolve in DMF, higher solubility solvent such as DMAc is utilized. Same as DMF, we use salts such as LiBr or LiCl to elute polymer more effectively. If you need help with analysis, please send us a request by submitting ‘Application Form’ under ‘Contact Us’ tab, and supervising researcher will aid you with a punctual and meticulous reply.
