Real time energy spectrum scanning electron microscopy is a device that integrates scanning electron microscopy and energy spectrum analysis technology. It can synchronously obtain surface morphology and elemental composition information of samples in real time, and has advantages such as high resolution, multimodal analysis, and convenient operation. It is widely used in materials science, biomedicine, industrial testing, and other fields.
function
Microscopic morphology observation: By scanning the surface of the sample with a high-energy electron beam, collecting signals such as secondary electrons and backscattered electrons to generate high-resolution images, the surface morphology and structure at the nanoscale can be observed.
Elemental analysis: The stimulated characteristic X-rays are analyzed through energy distribution to determine the types and contents of elements in the micro areas of the sample surface, supporting qualitative and semi quantitative analysis.
Real time synchronous analysis: Imaging and energy spectrum acquisition are carried out synchronously, which can obtain real-time information such as element distribution and content while observing the microstructure, avoiding the cumbersome process of traditional equipment "imaging first, then changing equipment to analyze components".
Intuitive visualization presentation: By using pseudo color imaging technology to convert element distribution into color maps, overlaid with SEM morphology images, the spatial distribution patterns of different elements in the sample are visually displayed.
Accurate detection: Fast scanning speed (some devices are equipped with 10M signal acquisition bandwidth), supports single pixel level element recognition, can accurately locate trace/trace elements, has small quantitative analysis errors, and has a high degree of automation in operation, making it easy for beginners to get started quickly.
Wide applicability of samples: compatible with various types such as metals, ceramics, battery materials, coatings, soft materials, biological samples, etc. Some equipment supports low vacuum mode, which can reduce the charging effect of insulation samples and does not require complex sample preparation.
Application scenarios
Materials Science and Nanotechnology: Analyze the element segregation of metal alloys, the compositional uniformity of ceramic materials, the dispersion state and elemental composition of nanoparticles, and support the development and performance optimization of new materials.
Electronics and semiconductor industry: detecting surface morphology defects of chips and integrated circuits, analyzing the composition and purity of semiconductor bonding wires, and investigating impurity elements in packaging materials.
In the field of batteries and new energy, observe the element distribution of positive/negative electrode materials for lithium batteries (such as silicon carbon negative electrode and nickel rich positive electrode), analyze the composition changes at the interface between electrolyte and electrode, and optimize battery performance.
Industrial quality control: Identify the material purity of metal products (such as rings and alloy components), test the coating thickness and composition uniformity, and investigate surface corrosion, inclusions, and other defects of materials.
Geology and Mineralogy: Analyze the microstructure and elemental composition of rocks and minerals, identify trace mineral phases, and assist in mineral resource exploration and geological research.
In the field of biology, observe the ultrastructure of cells and the surface morphology of biomaterials, and analyze the distribution of elements in biological samples.
