Microscopic investigation of embedded samples

By Karl Kersten - Jan 31, 2019

The purpose of embedding is to protect fragile or coated materials during preparation, and to obtain good edge retention. Embedding is also used to produce specimens of a uniform size, such as minerals, clay or other particles and can also be used to section a material and investigate its interior.

Why the plastics industry relies heavily on microscopy analysis

By Luigi Raspolini - Jan 24, 2019

Ever since oil became fundamental to industry, scientists and engineers from all around the world have carried out more and more research into how different organic molecules can be combined in certain patterns to obtain new materials with amazing properties. Commonly called plastics, they are known to the scientific community as polymers — chemical compounds with a highly-engineered chemical structure and composition. The analysis of these compounds is crucial in helping to improve polymer production processes. This article discusses how electron microscopy can provide the analysis that polymer developers need to improve product quality significantly.

Why SEM is a valuable technique for nanoparticle characterization

By Antonis Nanakoudis - Jan 10, 2019

The continuous increase of microscopic particles’ use in a huge range of applications has created the need of accurate control of their properties. I will explain why the use of precise monitoring and characterization of particles is required and how scanning electron microscopy can prove to be a valuable characterization method for you. Especially due to its versatility and superior spatial resolution.

Everything is nano these days: to improve the world of nanotechnology we make extremely fast SEM imaging and analysis accessible to everyone

By Karl Kersten - Dec 20, 2018

Imaging with a Scanning Electron Microscope (SEM) is a powerful tool for any materials scientist, though historically, accessing the technique was an issue. SEM involved using large, expensive systems that were only available to large research institutions. Even then, access was often difficult, due to long waiting lists and because their complex operation required in-depth training.

Imaging fibers with a SEM: how to obtain a flawless quality analysis

By Karl Kersten - Dec 6, 2018

In our daily life, we make use of a large amount of objects and devices that are produced from fibers. Fibers are usually imaged in a scanning electron microscope (SEM), which provides high-resolution images, elemental analysis, and the possibility of automatically measuring thousands of fibers in mere minutes.

But in some cases, imaging fibers with a SEM also presents challenges, as the nature of some fibers might compromise the quality of your analysis. With this in mind, this blog describes how you can obtain a high analysis quality through proper SEM configuration and sample preparation.

The revolution in asbestos analysis

By Luigi Raspolini - Nov 30, 2018

The detection of asbestos fibers is a complex and time-consuming operation, requiring the use of electron microscopes and highly trained operators. This results in high costs for the analysis and a slow throughput. What if the microscope could support the operator with an automated fiber detection routine and cut the time (and cost) required for each analysis? Find out how in this blog.

FEG source: what you need to know

By Karl Kersten - Nov 26, 2018

Until very recently, we have not seen a high kilovolt (kV) imaging desktop scanning electron microscope (SEM) with a Field Emission Gun (FEG) source in it. Why not? And why can it be useful to have a FEG source in a desktop SEM? This article provides some answers.

Sample preparation: how to disperse powder for amazing SEM images

By Willem van Zyl - Nov 16, 2018

The ability to analyze particles is becoming increasingly more important due to the rising prominence of additive manufacturing, leading to more stringent quality requirements for industrial manufacturers. Beyond maximizing yields, manufacturers need to ensure that their processes consistently deliver particles that have the appropriate size and morphology.
