简介：

　　The Renishaw structural and chemical analyser (SCA) shown in Figure 1 allows geologists and mineralogists to benefit from the imaging and analytical capabilities of scanning electron microscopes (SEMs) whilst combining the chemical and structural characterisation provided by Raman spectroscopy. The SEM-Raman system is unique, allowing both rapid observation and elemental analysis at macro and micro scale. An overview and detailed classification of the sample is now available in a single instrument.
