Product Synopsis

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.

.

Main Features

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.
