Laser Raman Spectroscopy
Because Raman spectroscopy is a scattering process, samples of any size or shape can be examined. Very small amounts of material can be studied down to microscopic levels (~1µm).
Renishaw InVia Reflex Raman Spectrometer with three wavelengths available: 785nm, 633nm and 514nm and two gratings, 1800 and 1200 l/mm. Also equipped with polarizer and half waveplate for each laser.
- Microscope with Macro Point Accessory Kit, allowing analysis of powders, liquids, and films
- StreamLine HR imaging, a high speed mapping function allowing the collection of thousands of datapoints in minutes. Minimum step size, 0.1 microns.
- StreamLine imaging, allowing the collection of spatially resolved spectra with longer accumulation times.
- Volume rendering (StreamLine HR acquisition)
- Depth profiling
Selected Applications in Industry:]
- Differentiation of carbon nanotube species (SWCNT, MWCNT)
- Identification of corrosion products on various metal surfaces
- Identification of different forms of carbon (e.g. diamond, graphitic, amorphous, diamond-like, nanotubes)
- Detection of different inorganic oxides and, in some instances, their crystal form
- Identification of micron-sized contaminants on photomasks
- Identification of pigments in some paints and inks
