The results can reveal information on crystal structure, phase composition, elemental distribution and other important properties of the samples studied, in the context of chemical analysis.
SEM-EDX (Scanning Electron Microscope) expertise: what are we talking about?
Scanning Electron Microscopy (SEM-EDX) is a laboratory microscopic analysis technique using a Field Emission Gun (FEG). This technique produces very high resolution images of the surface of a sample (magnification of the order of *1000000). It is a technique used to study the chemical composition and morphology of solid materials. The FILAB laboratory specialises in SEM-EDX expertise.
That’s why the FILAB laboratory has decided to equip itself with not one, but 3 SEMs! All three are also equipped with EDX probes for extremely precise analysis of your materials. These SEM-EDX techniques, with a column signal detection 20 times more intense than that of a conventional Scanning Electron Microscope, enable the FILAB laboratory to carry out high added-value analyses.

FAQ
SEM-EDX analysis is a microscopy technique used for imaging and analysis of elements and chemical composition. This technique combines scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). SEM-EDX analysis allows the surface structure and chemical composition of materials to be observed at high magnifications. The combination of these two techniques allows a detailed study of individual particles and surface characteristics of the material, which can be as small as 1 nanometre. The analytical information obtained from this analysis can provide valuable insights into the properties and characteristics of the sample in question. In addition, it can be used to identify contaminants or other impurities that may be present in trace amounts. SEM-EDX analysis is often used in a wide variety of applications, including materials science and forensic analysis. With this advanced technique, researchers can obtain precise information about the chemical composition of samples on a very small scale.
The SEM EDX analysis process begins by placing the sample in the chamber of an electron microscope. The electrons emitted from the sample then pass through an energy filter to produce secondary X-rays which are detected by the EDX detector. The energy dispersed X-ray data is then analysed to determine the composition and concentration of elements present in the sample. This analysis can provide accurate results on particle size distribution, crystal structures, oxidation states and other characteristics of individual particles.
SEM-EDX analysis is used in a wide range of industries including materials science, aerospace engineering, medical research, electronics manufacturing, environmental studies and forensic analysis. SEM analysis can be used to analyse and identify contaminants or other trace impurities in materials and components. It can also help researchers to better understand the surface characteristics of materials, such as particles or nanoscale structures. In addition, SEM-EDX analysis can provide valuable information on the composition and concentration of elements present in samples for a variety of applications. In addition, this microscopy technique has been successfully used by the pharmaceutical industry to detect active ingredients in drug samples with high accuracy.
EDX analysis (Energy dispersive X-ray (EDX) analysis) or EDX-analyse is performed using an EDX probe. This is a spectroscopic instrument, using X-rays to explore the chemical properties of elements present in a material. Combined with other complex material failure analysis techniques, EDX probes help analysts to understand the cause of material deterioration, and to develop appropriate solutions to prevent such material failures. Laboratories such as FILAB offer in-depth material failure analysis using EDX analysis equipment..
The EDX probe or EDX detector receives photons emitted by the material following electronic excitation by a special device. The EDX probe then measures the energy generated by the material. Each chemical element has a characteristic energy value, making it possible to identify the elements contained in the material.
Based on physico-chemical detection, an EDX probe is a laboratory tool for analyzing different types of materials. The materials that can be analyzed with an EDX probe are varied, from steel to polymers to metal alloys, but also glass, powder …
Recourse to this analysis is made following various problems: identify material family, metal microstructure, powder morphology or explore surface coating or defects, pollution, corrosion, material cracking…
This technology is very useful for characterizing the properties of materials, for example, to determine their composition, purity or concentration of specific elements. It is therefore the tool of choice in our laboratory for accurate and reliable analysis of materials.
SEM-EDX analysis can provide several types of information relating to materials and surface characterization :
- Imaging: scanning electronic microscope provides detailed images of the sample surface, revealing its topography and structure on a microscopic scale.
- Elemental composition: Energy Dispersive X-ray Spectroscopy (EDX-analyse)determines the chemical elements present in the sample, and their relative quantities. This makes it possible to identify the constituent elements of a material, or to detect the presence of specific elements.
- Elemental mapping: SEM-EDX analysis can also generate elemental distribution maps in the sample, enabling the spatial distribution of chemical elements to be visualized.
EDX stands for Energy Dispersive X-ray Spectroscopy. It's a technique used for elemental analysis or chemical characterization of a sample.
EDX analysis is a technique used to determine the elemental composition of materials. By measuring X-rays emitted from a sample when bombarded by electrons, EDX identifies and quantifies the elements present. This analysis is essential for research and quality control across various scientific and industrial fields.
What are the differences between SEM EDX and EDX in terms of analysis ?
SEM-EDX combines the high-resolution imaging capabilities of Scanning Electron Microscopy (SEM) with the elemental analysis provided by Energy Dispersive X-ray Spectroscopy (EDX).
SEM focuses on generating detailed images of material surfaces up to the nanometer scale, revealing texture and morphology, while EDX characterizes the elemental composition by analyzing the X-rays emitted from the material when bombarded with electrons.
Together, SEM-EDX offers a powerful tool for simultaneously understanding both the physical structure and chemical properties of materials, important for fields like materials science and semiconductor research.
EDX analysis is a method used for identifying and quantifying the elemental composition of materials. It is applicable to a broad range of samples and materials, including:
> Metals and Alloys: EDX can determine the elemental makeup of metallic samples, useful in metallurgy for quality control, alloy development, and failure analysis.
> Semiconductors and Electronic Components: It helps in the analysis of materials used in electronic and photonic devices, checking for impurities or composition accuracy.
> Biological Samples: In biology and medicine, EDX can be used to study the distribution of elements within tissues, cells, or bioengineered materials, often to understand physiological processes or disease mechanisms.
> Polymers and Plastics: EDX can also be used to analyze the presence of additives or contaminants in synthetic materials.
> Ceramics and Glasses: Analyzing ceramic materials or glass to determine their elemental composition, which is critical for understanding their properties and performance.
> Environmental Samples: EDX can analyze particles collected from air or water samples to identify pollution sources or environmental contaminants.
EDX is particularly valued for its non-destructive nature and its ability to perform localized analysis, providing elemental data from very small areas (micrometer scale), which is essential for materials research and quality control across these diverse fields.
