The Optilab® T-rEX™ (refractometer with EXtended range) is a Refractive Index 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 T-rEX™ achieves an unprecedented combination of sensitivity and range. 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 Optilab® T-rEX™ also has a flow cell with a total volume of only 7.4 µL — 25% less than the leading refractometers available today. This translates into minimized band broadening and better temperature stability.
The Optilab® T-rEX™ can also do something no other on-line Refractive Index detector can: it can measure the absolute refractive index of a solution. In addition, it can measure the dn/dc of a solvent at the same wavelength of light as the light scattering instrument. And just to make sure it can't be matched, you can replace the light source in the T-rEX™ for other wavelengths (e.g. 690, 633, 488, etc.)!
The new Optilab® T-rEX™ shares the ability of its predecessor (the Optilab® rEX) to go to below ambient temperatures as easily as above ambient. No hassle temperature control can be programmed down to 4°C or as high as 50°C. Compatible with all HPLC systems
