Why use Raman?
Although Raman spectroscopy has been recognized as a light scattering process since 1928, other techniques such as NMR, FTIR and UV-Vis have been more widely adopted in materials and chemical analysis laboratories. Raman has come of age in the recent past due to developments of lasers, optics and detectors, bringing this extremely information rich technique into the everyday analytical lab for chemical identification, the characterization of molecular structures, crystallization, molecular bonding, stress and environmental factors.
Raman microscopy provides spatial resolution down to the sub-micron level and enables confocal microscopy to examine layered materials. Raman imaging enables you to map chemistries across areas of a sample to identify inclusions, contaminants, homogeneity or interfaces.
Raman offers several advantages over other spectroscopic techniques
- Raman is generally non-destructive and requires little or no sample preparation
- Raman easily samples through glass or plastic containers
- Raman does not suffer from the water absorption effects, making it ideal for examining aqueous solutions
- The intensity of spectral features in solution is directly proportional to the concentration of the particular species
- Raman spectra are generally robust to temperature changes
- Raman is sensitive to symmetric bonds and is good for characterizing molecular backbones
- Raman is sensitive to even slight changes in bond angle and strength for characterizing geometric structure
- Raman is highly sensitive to stresses in molecules or modifications that affect bond properties
Add Raman to existing techniques
The Thermo Scientific iXR Raman spectrometer is designed for multi-modal use with techniques such as X-ray Photoelectron Spectroscopy, SEM/EDS and rheology. Coupling the iXR module to your technique enables concurrent measurements at one location. One measurement provides answers from multiple techniques all taken at the same time and in the same conditions. Learn about your samples physical, chemical and structural characteristics and how they affect one another from one measurement.
The iXR spectrometer uses the same lasers, gratings and filters as the DXR2 family of spectrometers, making it a versatile complement in multi-technique, multi-user laboratories.
