eRPHiX is an experimental mobile field lab instrumentation platform capable of fast hyperspectral imaging of the plasmonic effect of Raman active organic composites in enhancing colloidal liquids or nano-substrates.
The platform is intended to facilitate the verification of sensitivity and reproducibility of SERS-substrates and the development of novel solutions.
It addresses a need of research labs and nanomaterials manufacturers.
The present functional prototype enables the detection and dynamic hyperspectral
imaging of Raman spectra in:
· solids, powders and liquids at a min. 10% concentration and
· surface enhanced plasmonic Raman spectra of low concentration of organic volatiles in droplets of colloidal solutions on glass slides or solid nano-substrates
The unit has a GigE interface and can be easily connected to state-of-the-art hyperspectral imaging software packages for further data evaluation and modelling.
It comes in a robust transportation case, is fast to build up and versatile in use, either in horizontal or vertical standing; SERS droplets are scanned in the present version on a microscope slide in vertical standing only. Customized adaptations are easy to implement.
