材料科學

Material science provides a varied and challenging range of samples for spectroscopic analysis which is ideally suited to the versatility offered by Renishaw's inVia Raman microscope. Typical materials include composites, polymers and catalyst reagents. Many of these samples can benefit from a second, complementary analysis technique, such as the pioneering structural and chemical analyser, or SEM-SCA, a combination of scanning electron microscope (SEM) and microRaman capabilities

For example, a recent case study involved the use of Renishaw Raman technology to investigate a crack in a steel component from a nuclear reactor. It was thought, and confirmed by initial microRaman analysis, that the cracking was caused by oxidation induced brittleness. In order to understand more fully the processes involved in this degradation, and hence allow preventative steps to be initiated, a more detailed analysis was required. The large depth of field and chemical analysis on the micron scale afforded by the SEM-SCA successfully facilitated this specific analysis.
