The Optilab® UT-rEX™ UHPLC Refractometer with EXtended Range

The Optilab® UT-rEX (UHPLC refractometer with EXtended range) from Wyatt Technology is the first RI detector that can be coupled with any UHPLC unit. The device is designed to operate alone as a universal concentration detector, or in combination with the Wyatt µDAWN multi-angle light scattering (MALS) detector. It is also capable of measuring absolute molar mass and size of nanoparticles and macromolecules in solution through µSEC-MALS.

The Optilab® UT-rEX can measure macromolecules and nanoparticles from 10 to 50nm in size and 200Da to 10MDa in molar mass when integrated with the µDAWN.
