Advanced detectors for challenging chromatography applications

Jan 09 2024

Testa Analytical offers a selection of Differential Refractive Index (DRI) detectors proven to elevate the performance of GPC/SEC, HPLC, or UHPLC systems. Recognised for measuring analyte refractive index relative to the solvent, the high-performance DRI detector is acknowledged as one of the most versatile detectors for liquid chromatography applications.

The stability of the baseline signal in any liquid chromatography detector is crucial, especially in peak determination. This stability becomes even more critical in long analysis times, commonly encountered in high-resolution applications. Testa's DRI detector operates from room temperature up to 80°C, demonstrating high thermal stability and a meticulous design aimed at eliminating drift. With unmatched baseline stability, the DRI detector excels in challenging chromatographic separations.

Manufactured, designed, and rigorously quality-tested in Germany, Testa Analytical's DRI detectors are available with competitive delivery times.
