WYATT Technology WOP1-01 HPLC Refractive Index Detector

Cambridge Scientific ID: 28587 Category: Tag:

Description

Using a combination of cutting-edge semiconductor photodiode technology and proprietary computer algorithms, the Optilab achieves an unprecedented combination of sensitivity and range. These features mean that it addresses both standard chromatographic applications and some challenges unique to light scattering measurements such as high concentrations, determination of sample refractive increments (dn/dc) and solvent refractive index.
