Based on decades of experience in the chromatography field, Testa Analytical Solutions has designed a Differential Refractive Index (DRI) detector kit adaptable to fulfil the specific demands of different HPLC system manufacturers.
Despite their limited sensitivity, compared to other detectors such as UV or MS, the ability of DRI detectors to detect any analyte with a refractive index different to the solvent makes them the detector of choice for HPLC applications ranging from small molecules to proteins, petroleum additives, polysaccharides, and synthetic polymers.
The HPLC DRI detector kit comprises a total of five separate modules (opto-electronics, fluidics, temperature control, electronics, and firmware) each capable of customisation and adaptation. The simple selection of optimised modules to best suit different instrument designs enables Tests to provide an optimised DRI detector for almost any HPLC or uHPLC system.
Once the optimal modules are selected and defined, a customer specific HPLC DRI detector is created using a carefully controlled (and documented) process. The aim is that the DRI detector developed for the user's HPLC system is capable of dominating its intended targeted markets.
