- Investigation of Surface Structures with Scanning Electron Microscope
The determination of chemical composition and surface structure is usually a significant factor when processing surfaces. Surface structure and morphology have a bigger role in solving challenges in specific circumstances. Furthermore, tracking changes in surface structure, distinctive features, or specific locations on the surface of coated items can aid in understanding and adjusting surface characteristics. Defect classification is also important for identifying possible origins of surface structure alterations.
However, it is critical not to rely just on the outcomes of a single method, but to integrate them. Alfa Chemistry relies on the precision of XPS and ToF SIMS instruments, but we also use SEM to assist our customers in solving challenges.
SEMs work in the same way as optical microscopes, however, they illuminate using electron beams rather than light waves. SEM images are created by scanning a focussed electron beam across the sample's surface. The detected low-energy secondary electrons are employed to regulate the brightness of the synchronized scanning CRT in the SE picture mode. X-rays and other emission signals can be detected and used to characterize the material. The primary electron beam detects these X-ray energies, which are indicative of the sample's elemental makeup, enabling both qualitative and quantitative element analysis.

The following information is available:
We offer scanning electron microscope services for examining surfaces and particles, coating failure analysis, texture and morphology visualization, and material contamination. Alfa Chemistry's scientists have amassed extensive industry knowledge that may assist you in solving problems, performing quality control, and vastly improving your material understanding.
Using SEM to investigate various surfaces, our experts generate high-resolution images for associated observations and measurements. They can also inspect the sample's inner structure using various cross-sectional processes. By cooperating with you, we will be able to provide you with substantial insights based on our years of sample preparation and analysis knowledge.
Alfa Chemistry uses a combination of scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) to reveal morphology, layer structure, and chemical composition, not just for the average surface area, but also for particular surface features.
The benefits of our SEM-EDX analysis technology include but are not limited to:
