Refractive index detector
Jun 2006Wyatt Technology Corp.Request Info
Based on semiconductor photodiode technology and
proprietary computer algorithms, the Optilab rEX refractive index detector from
Wyatt Technology Corp. can measure the absolute refractive index of a solution as
well as the dn/dc of a solvent at the same wavelength as the light-scattering instrument.
The device has no range or gain settings, and the full range of detection is always
in view. It has a flow cell with a total volume of 7.4 μl, resulting in minimal
band broadening and greater temperature stability. Its light source can be replaced
to accommodate other wavelengths.
