TESTA Analytical Solutions e.K. has designed a Differential Refractive Index (DRI) detector kit adaptable to fulfil the specific demands of different HPLC system manufacturers.
Despite limited sensitivity when compared with, for example, UV or MS detectors, the ability of DRI detectors to detect any analyte with a refractive index which is different from the solvent makes them suitable for HPLC applications ranging from small molecules to proteins, petroleum additives, polysaccharides, and synthetic polymers.
The TESTA Analytical HPLC DRI detector kit comprises five separate modules (opto-electronics, fluidics, temperature control, electronics, and firmware), each capable of customisation and adaptation. The ability to select optimised modules which best suit different instrument designs enables TESTA 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.
