Wavelength Optimized dn/dc Measurement
The most accurate method of determining dn/dc is to use a stand-alone batch instrument, such the HK Series differential refractometer, and to take measurements at different concentrations. While this uses more sample than on-line methods, it is not influenced by chromatographic parameters.
The HK Series differential refractometer is a flexible device that may be used in either static or dynamic mode. In static mode, the specific refractive index (dn/dc) of dissolved samples can be easily and precisely determined in just a few minutes. Beneficially, the system now offers a large number of wavelength options enabling precise matching of your light scattering detector laser operating wavelength, thereby ensuring reliable and reproducible results every time.
