TESTA Analytical’s Differential Refractometer uses light scattering techniques to improve the precision of dn/dc determination.
An accurate dn/dc value is essential in molecular weight determination of biopolymers and polymers by light scattering. The Differential Refractometer enables fast determination of the specific refractive index increment (dn/dc) of dissolved samples accurately and rapidly. Without any limitations in terms of solvent and with a wide range of measurement temperatures, the system offers multiple wavelength options to enable precise matching of light scattering instrument laser operating wavelength to ensure reliable and reproducible results.
It operates via a PC using intuitive Windows based software which can also determine the accurate concentration of samples with known dn/dc. Samples can be recovered without dilution or pollution, direct use for Light Scattering, saving time and reducing errors.
