Extended Range Refractometer

The Optilab rEX is an RI detector with 256 times the detection power and up to 50 times the dynamic range of current RI detectors. Using a combination of semiconductor photodiode technology and proprietary computer algorithms, the rEX features multiple instrument firsts. For example, there are no range or gain settings. The full range of instrument detection is always present, and the full sensitivity exists over the entire range. The rEX also has a flow cell with a total volume of only 7.4 μL, which translates into minimized band broadening and better temperature stability. The device can also measure the absolute refractive index of a solution and shares the ability its predecessor (the Optilab DSP) to go to below ambient temperatures as easily as above ambient.
