The specific refractive index increment (dn/dc) is one of the most underestimated parameters in polymer and protein science, small errors in its calculation can have a huge impact on molecular weight values determined by light scattering experiments. Learn how our HK Series Differential Refractometer sets a new standard for precise determination of dn/dc.
