HPLC-optimised DRI detectors

With decades of experience in separation science, Testa Analytical provides Differential Refractive Index (DRI) detector kits specifically optimised to meet the unique requirements of different HPLC system manufacturers.

“Even in a world where so much has already been invented, developing an HPLC detector with market-leading performance can be a costly and complex challenge,” said Carlo Dessy, Technical Director at Testa Analytical. “By consulting our team of experienced chromatographic innovators, clients can enhance both the economic and technological competitiveness of their instruments. DRI detectors remain a top choice for HPLC applications because they can detect any analyte with a refractive index different from the solvent - ranging from small molecules and proteins to petroleum additives, polysaccharides, and synthetic polymers.”

Drawing on expertise in opto-electronics, fluidics, temperature control, electronics, and firmware, Testa Analytical has a proven track record of designing and delivering optimised DRI detectors tailored to the specifications of different HPLC suppliers and application niches.

These detectors combine reliability, sensitivity, and flexibility, giving laboratories and instrument manufacturers the tools to meet demanding analytical challenges with confidence.
