Besides UV, mass spectrometry and evaporative light scattering, there has been no RI detector available for UHPLC applications until now. The linearity of the instrument over a wide range, coupled with its sensitivity to samples that are not UV active, make it an exciting addition to UHPLC. Besides UV, mass spectrometry and evaporative light scattering, there has been no RI detector available for UHPLC applications until now.
The linearity of the instrument over a wide range, coupled with its sensitivity to samples that are not UV active, make it an exciting addition to UHPLC. Due to the extremely small volumes of UHPLC, the dead volume for the instrument is <1.5µl as compared to 10-20 µl for other RI detectors. As a result, the UT-rEX also offers superior resolution which will not be compromised.
In addition to the instrument having no range or gain setting, the full range of instrument detection is always present and the full sensitivity exists over the entire range. The small flow cell and proprietary temperature regulation enable stable RI baselines and RIS signals which further enhance the detector’s sensitivity.
The Optilab UT-rEX can be operated 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. The Optilab UT-rEX is compatible with all UHPLC systems.
