The analytical electron microscope (AEM) uses a high energy (>100 kV) beam of electrons to generate a range of signals from a thin foil sample as shown in figure la [1,2]. Various detectors are configured in the AEM to pick up most of the generated signals (fig. lb). Microanalysis is usually performed using the characteristic x-ray signal, detected by an energy dispersive spectrometer (EDS) alt...

This article summarizes the basic principles of electron probe microanalysis, with examples of applications in materials science and geology that illustrate the capabilities of the technique. Handbook of instrumental techniques from CCiTUB Electron probe microanalysis

Recent developments in SEM column design have led to the ability to produce nm spot sizes even at high probe currents [1], thus pushing the analytical techniques available in the SEM to conduct microanalysis with nanometer resolution. Although the limitations of microanalysis at these spatial resolution requirements stem from the physics of beam-specimen interaction and the volume from which th...

Cathodoluminescence ~CL! microanalysis provides high-sensitivity spectra and high-resolution images associated with impurity and structural defects at the nanoscale and from luminescent materials including minerals, semiconductor, and dielectric/insulating materials. Cathodoluminescence is the non-incandescent emission of light ~photons! emitted from materials excited by an electron beam. CL ph...

AIM To develop methods of articular cartilage preparation for X-ray-electron probe microanalysis and to study its elements content in experimental osteoarthrosis. METHODS Twenty dogs aged 2-8 years were divided in research (aged 2 years, induction of osteoarthrosis - IOA) and intact group. Intact group included three subgroups (aged 2, 5 and 8 years). Samples of cartilage after araldite satur...

The impact of electron probe microanalysis on the study of geological and planetary materials has been tremendous. Electron microprobes evolved into routine analytical instruments in geological research laboratories as instrument capabilities improved and applications to geologic/planetary materials expanded. The contributions of electron probe microanalysis to the characterization of minerals,...

The National Institute of Standards and Technology (NIST) has been involved in the development of standards for microanalysis since the middle of the 1960s. Certification of "traceable" standards that can be sold to other laboratories is time-consuming and costly, especially when the extent of microheterogeneity within each specimen becomes part of the uncertainty assigned to the certified valu...
