$Instrument optimized Differential Refractive Index detectors$

Based on decades of experience in the separation science field, TESTA Analytical is a leading supplier of Differential Refractive Index (DRI) detector kits optimized to fulfil the specific demands of different HPLC system manufacturers.

Carlo Dessy, technical director of TESTA Analytical said “In a world where everything has been already invented, optimized, perfected, creating an HPLC detector with market-leading performance specifications, can be an expensive and challenging task, even for the most experience R&D teams. Having access to our team of experienced chromatographic innovators offers clients the opportunity to impact their competitiveness both from an economic as well as technological point of view. While they have been available for some time the ability of DRI detectors to detect any analyte with a refractive index different to the solvent makes them a detector of choice for HPLC applications ranging from small molecules to proteins, petroleum additives, polysaccharides, and synthetic polymers. Consequently, being able to offer a high performing DRI detector is appealing to all HPLC system manufacturers”.

Based upon expertise in opto-electronics, fluidics, temperature control, electronics, and firmware - TESTA Analytical has a proven track record of creating and delivering optimized DRI detectors for different HPLC system suppliers and application niche.
