Traditionally, SEM images were grayscale, focusing on topographical contrast. With the advent of Color SEM, it's now possible to introduce pseudo-color to these images. This helps in: 1. Visual differentiation: Different shades can represent different elements or phases, making it easier to distinguish components of a complex sample. 2. Enhanced Image Interpretation: Color can highlight features that might be overlooked in grayscale, making analysis more intuitive.
Energy Dispersive Spectroscopy (EDS) is a technique that identifies and quantifies the elemental composition of a sample. When the sample is bombarded with electrons: • X-rays are emitted. • EDS detectors capture these X-rays. • A spectrum is generated, revealing the elements present.
When Color SEM and EDS are used in conjunction: 1. Locate Areas of Interest: With the detailed visual aid of Color SEM, researchers can pinpoint specific areas or features of interest. 2. Elemental Analysis: Once a region is identified, EDS can be employed to determine its elemental composition. 3. Correlative Imaging: Color SEM images can be overlaid with EDS elemental maps, providing a comprehensive view of both structure and composition.
This combined technique is invaluable in numerous fields:
SEM analysis provides the morphology of sample. EDS identifies the elements in the sample.
Color SEM and EDS together provide a powerful toolkit for researchers and professionals across various disciplines, transforming the way we understand and analyze microscopic deposits. Our mission is to deliver efficient, cost effective answers to your materials questions through SEM/EDS services, and micro FT-IR analysis. Same day or next day service can usually be scheduled. We want to help metallurgists, materials specialists, manufacturers, engineers, quality assurance managers, attorneys, and designers find solutions to material and quality problems.
