The HK Series Differential Refractometer from Testa Analytical Solutions e.K aims to set a benchmark for precise determination of specific refractive index increment (dn/dc) – an important parameter for polymer and protein molecular weight determination using light scattering techniques.
The flexible device may be used in either static or dynamic mode – the latter of which can easily and precisely determine the specific refractive index (dn/dc) of dissolved samples in just a few minutes. The system features a large number of wavelength options, enabling precise matching of the light scattering detector laser operating wavelength and ensuring reliable and reproducible results.
Where the dn/dc value of the sample is already known, the refractometer can be used for precise and sensitive concentration determination. The sample can then be easily recollected and utilised for further investigations.
