Differential Refractometer
Differential Refractometer improves light scattering molecular weight determination.
Backed by decades of experience of Gel Permeation Chromatography (GPC) and Light Scattering techniques, Testa Analytical has created a differential refractometer accessory for light scattering instruments that deliver exceptional performance and is easy-to-use.
The Differential Refractometer is a flexible device which allows fast determination of the specific refractive index increment (dn/dc) of dissolved samples with extremely high accuracy and in just a few minutes. Without any limitations in terms of solvent and with a wide range of measurement temperatures, it is a true workhorse and a valuable addition to any Light Scattering lab. Beneficially, the system also offers different wavelength options enabling precise matching of your light scattering instrument laser operating wavelength, thereby ensuring reliable and reproducible results every time.
