Why SEM Matters for Researchers and Industry Professionals
For researchers and industry professionals, achieving high-resolution imaging, precise measurement, and accurate material characterisation is critical. Traditional optical microscopy often fails to resolve fine structural details, measure microfeatures, and identify material compositions.
Scanning Electron Microscopy (SEM) addresses these challenges by offering nanometer-scale imaging, automated measurement capabilities, and elemental analysis through Energy Dispersive X-ray Spectroscopy (EDS). These capabilities make SEM essential in materials science, energy storage, electronics, life sciences, and forensics.
At BlueScientific, we distribute Thermo Scientific Phenom SEM solutions in the UK and Ireland, tailored for both research and industrial applications. This blog explores how SEM helps overcome key challenges in microscopy and materials analysis.
Thermo Scientific Phenom SEM Solutions
Challenge 1: Achieving High-Resolution Imaging for Micro & Nanoscale Research
The Limitations of Optical Microscopy
Traditional optical microscopes are constrained by the wavelength of light, limiting their resolution to around 200 nanometers (nm). This makes it challenging to analyse features at the micro- and nanoscale, which are critical in fields such as:
- Materials Science – Investigating nanomaterials, thin films, and composite materials.
- Life Sciences – Examining cell structures, bacteria, and biomaterials.
- Electronics – Assessing semiconductor surfaces and microchip defects.
How SEM Overcomes These Limitations
SEM uses a focused electron beam rather than light, providing far greater magnification and depth of field. Advanced models such as the Thermo Scientific Phenom Pharos G2 achieve resolutions below 2 nm, revealing nanoscale surface structures with exceptional clarity.
Key Advantages of SEM Imaging:
- Higher resolution than optical microscopy.
- 3D surface visualisation for in-depth structural analysis.
- Backscattered electron (BSE) imaging to highlight compositional differences.
By offering nanometer-scale imaging, SEM enables scientists and engineers to conduct more detailed investigations, ensuring better insights into material behaviour and structural integrity.
Challenge 2: Precise Measurement of Microstructures Surface Features
The Need for Reliable Dimensional Analysis
In research and manufacturing, precise measurement of microscopic structures is essential for quality control, material characterisation, and failure analysis. Traditional measurement techniques often struggle with irregular or complex microstructures.
How SEM Enables Precise Measurements
SEM systems are equipped with automated measurement tools that accurately determine:
- Particle size and shape distributions (used in pharmaceuticals, coatings, and nanomaterials).
- Microstructure dimensions in batteries, metals, and composite materials.
- Surface roughness in automotive coatings and industrial manufacturing.
For example, SEM is widely used in lithium-ion battery research to examine graphite particle morphology, which directly affects battery performance and lifespan.
By integrating software solutions for automated analysis, SEM ensures repeatable, accurate measurements, reducing human error and improving research efficiency.
Challenge 3: Understanding Chemical Composition for Material Characterisation
Why Material Identification is Critical
In many applications, knowing the chemical composition of a sample is just as important as its structural properties. Identifying contaminants, verifying alloy compositions, or mapping elemental distribution are common challenges across multiple industries.
How SEM with EDS Enables Chemical Analysis
By integrating SEM with Energy Dispersive X-ray Spectroscopy (EDS), users can:
- Identify unknown materials at the microscopic scale.
- Detect contamination in failure analysis.
- Perform elemental mapping to visualise material distribution.
The Thermo Scientific Axia ChemiSEM takes this a step further by processing SEM and EDS signals simultaneously, allowing for live elemental analysis without complex post-processing.
Key Advantages of SEM with EDS:
- Real-time material composition analysis.
- Non-destructive testing for sample integrity.
- Automated workflows for faster, more efficient research.
This capability is essential in failure analysis, semiconductor research, metallurgy, and forensic science, where understanding material composition is crucial for decision-making.
