State of the Art Microanalysis Using Raman Microscopy
Introduction Raman spectroscopy is one of the most common techniques for materials identification and characterization. Based on inelastic scattering of a monochromatic excitation source, Raman measures vibrational, rotational and other low-frequency modes in a system. It’s not only characteristic for functional groups, but also sensitive to backbone and crystalline structures. Therefore, Raman...
متن کاملTheoretical Study of the Spatial Resolution of X-ray Microanalysis in Analytical Electron Microscopy
The spatial resolution of X-ray microanalysis has been investigated by Monte Carlo calculatio~s, including knock-on secondary electron production. The results for AuMa in a lOOOA thin Au film at 100 keV showed an appreciable difference from the ones without knock-out events. Also calculations have been done with the Mott cross-section instead of the screened Rutherford cross-section for elastic...
متن کاملElectron Microscopy and X-ray Scanning Microanalysis of Needle Biopsy Material from Human Liver
A study has been made of the fine structure of hepatic parenchymal cells of human biopsy material in a case of pancreatic tumor with obstructive jaundice. Dense particles about 60 A in diameter have been found in the cytoplasm, which are considered to be ferritin molecules by electron microscopy. They are encountered throughout the cytoplasmic matrix and are often aggregated in electron-transpa...
متن کاملElectron probe X-ray microanalysis of cultured epithelial tumour cells with scanning electron microscopy.
Three methods have been used to prepare cultured cells for electron probe X-ray microanalysis (EPXMA): (1) analysis at the subcellular level of freeze-dried ultrathin cryosections with scanning transmission electron microscopy (STEM); (2) analysis at the cellular level of whole freeze-dried cells with STEM; and (3) analysis at the cellular level of whole freeze-dried cells with scanning electro...
