Wyatt Technology Optilab dRI Refractive Index Detector WOP1-01

The Wyatt Technology Optilab dRI Detector WOP1-01 is a high-precision refractive index detector for liquid chromatography, polymer analysis, protein quantification, and concentration monitoring. It measures absolute refractive index values for compounds that may have limited or no UV absorption and can be coupled with light-scattering systems for molecular weight determination.
