The Optilab ™ is a unique dRI detector for standard HPLC/GPC with 256 times the detection power and 50 times the dynamic range over alternative RI detectors for chromatography. This detector measures the solvent's absolute refractive index, a requirement for MALS calculations, at the same wavelength as the MALS detector, for maximum accuracy.The Wyatt Optilab rEX is configured as a standalone differential refractometer, used principally to measure the specific refractive index increment (dn/dc) of polymer solutions; dn/dc is a required parameter for analysis of data from the light scattering detectors on our two GPCs. Ordinarily, the Optilab rEX is configured with a 658 nm fiber-optic laser diode source, but we also have .The Optilab™ is a unique dRI detector for standard HPLC/GPC with 256 times the detection power and 50 times the dynamic range over alternative RI detectors for chromatography. This detector measures the solvent's absolute refractive index, a requirement for MALS calculations, at the same wavelength as the MALS detector, for maximum accuracy. . The Optilab rEX (refractometer with EXtended range) is an RI detector with 256 times the detection power and up to 50 times the dynamic range of every RI detector in existence today. Using a combination of cutting-edge semiconductor photodiode technology and proprietary computer algorithms, the rEX presents a host of instrument firsts.

The term dn/dc, also called the “specific refractive index increment”, represents the change in the refractive index (dn) of a solution with respect to a change in its solute concentration (dc).The measurement of dn/dc is an essential parameter required to analyze multi-angle light scattering for the absolute characterization of molar mass.The dn/dc value is unique for each .

独自のdRI検出器. Optilabは、標準のHPLC / GPC用のユニークなdRI検出器であり、現在存在するクロマトグラフィー用の他のすべてのRI検出器の256倍の検出力と、50倍のダイナミックレンジを備えており、MALSとの接続に価値のある追加検出器になります。The Optilab differential refractometer is capable of measuring dRI online or offline, and in addition to meas-uring unknown concentrations, it can be used to deter-mine dn/dc. Since the Optilab is used in combination with a DAWN , miniDAWN or microDAWN MALS instrument for molar mass determination, the fact that Wyatt Technology Optilab DSP Interferometri c Refractometer.
