The Optilab® UT-rEX™, an UHPLC refractometer with an extended range is the first RI detector especially designed to be used with any UHPLC system. It works in combination with the Wyatt µDAWN™ multi-angle light scattering (MALS) detector or alone as a universal concentration detector to determine the absolute molar mass and size of macromolecules and nanoparticles in solution, through µSEC-MALS.
Along with the µDAWN™, the UT-rEX can determine macromolecules and nanoparticles from 10-50 nm in size and 200Da – 10MDa in molar mass.
The key features of the Optilab® UT-rEX™ Refractive Index Detector are:
- Range: -0.0047 to +0.0047 RIU
- Sensitivity: 1.5•10-9 RIU
- Temperature control both above and below ambient, from 4°C - 65°C
