Universal Detector for Challenging Chromatography Applications

Differential Refractive Index detector optimized for GPC/SEC applications.

TESTA Analytical offers a range of Differential Refractive Index (DRI) detectors designed and proven to enhance the performance of almost any GPC/SEC, HPLC or UHPLC system.

Measuring the refractive index of an analyte relative to the solvent – a high-performance Differential Refractive Index (DRI) detector is widely acknowledged as one of the most flexible detectors for liquid chromatography use.

The baseline signal stability of any liquid chromatography detector is particularly important, as it is a limiting factor in peak determination. Detector stability gains even more importance where analysis time is long, such as is commonly encountered in high resolution applications. Operating from room temperature up to 80°C with high thermal stability, TESTA’s DRI detector has been designed with particular attention to eliminating drift. As a consequence of its unmatched baseline stability, the DRI detector delivers excellent performance for even challenging chromatographic separations.

Designed, manufactured and quality tested in Germany – TESTA Analytical DRI detectors are available on competitive delivery times.
