Two Renishaw confocal Raman and fluorescence microspectroscopy systems provide non-destructive detailed insight into the chemical and structural nature of material. The Renishaw Invia Qontor system includes multimodal Stokes and anti-Stokes, as well as low frequency, Raman and fluorescence, electroluminescence, and photocurrent additional capabilities.
Applications
Typical applications include microbiology, drug delivery, cancer research, redox and plant biology, 2D materials, nanotechnology, photovoltaics semiconductors, battery, corrosion, catalysis (electrochemical, thermal), polymer, oxide, and electrolyte.
Specifications
System tracks and correlates spatially-temporally resolved chemical and structural information near-surface, including changes in the interfacial mass (EQCM) during electrochemical reaction, changes in structure under current flow (PV, OLED, memristors).
