Optimised differential refractive index detectors 

Testa Analytical has drawn on decades of separation science expertise to deliver Differential Refractive Index (DRI) detector kits optimised for different HPLC platforms. Designed for precision, stability, and broad compatibility, these detectors meet the demanding performance requirements of modern chromatographers.

“Creating a DRI detector with market-leading specifications is a complex task, even for experienced R&D teams,” said Carlo Dessy, Technical Director at Testa Analytical. “By providing optimised solutions tailored to HPLC system manufacturers, we help clients enhance both technological performance and cost efficiency.”

DRI detectors remain a detector of choice for applications spanning small molecules, proteins, petroleum additives, polysaccharides, and synthetic polymers, thanks to their ability to detect any analyte with a refractive index differing from the solvent.

Testa Analytical’s proven expertise across opto-electronics, fluidics, temperature control, electronics, and firmware enables the creation of high-performing, application-specific detectors that integrate seamlessly with different HPLC systems. The result is enhanced accuracy, reliability, and versatility across a wide range of analytical applications.
