Limited tender spectrometer for bio chemical molecular analysis

Tenders are invited for the requirement of a spectrometer for bio/chemical molecular analysis integrated with a light source and flow system. The bio/chemical molecular analysis to be monitored using a sensor that is sensitive to refractive index changes based on the principle of surface plasmon resonaance, grating or interferometry. The biomolecular interactions on a sensor surface as well as in liquid phase in a cuvette should be measured. The samples include bacteria, virus, proteins, antibodies, nucleic acids, polymers or heavy metals for detection.
