BERLIN, Germany, Dec. 28, 2018 — Differential RefractometerThe AYE Differential Refractometer from Testa Analytical Solutions eK is a high-performance instrument for chromatographic measurements.

In static mode, the specific refractive index increment (dn/dc) of dissolved samples can be easily and precisely determined in just a few minutes. The specific refractive index increment is a critical parameter required to determine absolute molecular weight using static light scattering (SLS) detectors because a relatively small error in dn/dc determination will lead to twice the error in calculating molecular weights.

The AYE differential refractometer offers a large number of wavelength options that enable precise matching of SLS detector laser operating wavelengths, thereby ensuring reliable and reproducible results every time.
