METHOD FOR GENERATING INTRA-PARTICLE MORPHOLOGICAL CONCENTRATION / DENSITY MAPS AND HISTOGRAMS OF A CHEMICALLY PURE PARTICULATE SUBSTANCE

摘要

Method for generating intra-particle morphological concentration/density maps and histograms of chemically pure particulate substances. Regular and focus-fusion multi-layer spectral imaging, combined with pattern recognition classification analysis are performed on individual particles for forming sets of single-particle spectral fingerprint data and spectra. Spectral shifts are identified in single-particle spectral fingerprint data, forming intra-particle region groups featuring sub-sets of intra- particle spectral fmgerprint pattern data and spectra. Each intra-particle region group is associated with different types of intra-particle morphological regions, where each region type is associated with a surface concentration value and a density value of the chemically pure substance in that imaged particle, for forming intra-particle morphological concentration/density data, which is used for generating an intra- particle morphological concentration/density map. Morphological concentration/density histogram, or frequency distribution, is generated from particle morphological concentration/density data, for illustrating global morphological distribution of concentration and density of the chemically pure substance throughout the entire multi-particle substance.
