Refractive Index detectors are widely used for the analysis of molecules with weak or no UV absorption. TESTA Analytical’s Differential Refractive Index (DRI) Kit for HPLC can be adapted to almost any ...

Testa Analytical Solutions e.K reports on growing interest in OEM versions of its Differential Refractive Index (DRI) detector to enhance the performance of both HPLC and GPC/SEC systems. Charlotte ...

refractive index (RI) detectors have enabled the discovery of testing materials that do not possess ultraviolet absorbance. Through the years, however, researchers have determined that RI ...

2) the refractive index (RI) detector measures changes in the refractive index of the eluent as it flows through the detector. This type of detector is highly sensitive to compounds that show little ...
