Confocal Raman Mapping
High-speed confocal Raman imaging, with improved sensitivity and resolution, is a powerful tool for the examination of a wide range of heterogeneous materials
Intertek MSG has recently acquired a new state-of-the-art confocal scanning Raman microscope, which is perfectly suited to the study of the spatially-varying chemical structures in materials as diverse as pharmaceutical tablets, carbon-fibre composites and surface coatings.
Key features of the new Raman instrument:
- High spatial resolution - typically around 1 micrometer
- High sensitivity - allowing for the rapid analysis of small or thin samples
- Multiple laser wavelengths (532, 633, 660 amd 785 nm) - enabling the examination of a wide range of materials. 785 nm is particularly suited to the study of fluorescent materials such as PEEK and epoxy
- Transmission Raman microscopy for accurate analysis of bulk samples including opaque or turbid materials (e.g. powders)
Typical applications of the instrument:
- Filled or composite materials
- Material morphology, including polymorph distributions, crystallinity and orientation
- Analysis of defects and contamination
- Study of mixtures and blends
- Surface coatings or treatments
- Distribution of active ingredients and excipients in pharmaceuticals
- Dynamics of process - e.g. real time cure monitoring in adhesives and stability studies of mixtures
- Non-destructive depth-profiling
This new instrument adds to the capability of Intertek's world-class team in the area of vibrational spectroscopy, led by Dr Neil Everall
