TESTA Analytical offers a range of Differential Refractive Index (DRI) detectors designed to enhance the performance of almost any GPC/SEC, HPLC, or UHPLC system, according to the company.
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 company says.
The baseline signal stability of any liquid chromatography detector is particularly important, as it is a limiting factor in peak determination, the company says. 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 baseline stability, the DRI detector supports challenging chromatographic separations, according to the company.
TESTA Analytical Solutions is a supplier of liquid chromatography instruments and detectors, drawing upon over 30 years of experience. Designed, manufactured and quality tested in Germany, TESTA Analytical DRI detectors are available on competitive delivery times, the company says.
