查询词典 DN

A theoretical formula is proposed for the refractive index increment correction of SEC chromatogram of polymer, which involves the molecular formula weights and the ratio of dn/ dc of the end group and the structural repeating unit. The refractive index increment ratio could be evaluated a priori by Lorenz-Lorentz or Gladstone-Dale equations.
