Buying a scanning electron microscope: how to select the right SEM

By Karl Kersten - Aug 2, 2018

You want to buy a new scanning electron microscope (SEM) because you know you need more SEM capability. Maybe you have a traditional floor model SEM, but it is slow and complicated to operate. Maybe you are using an outside service and the turn-around time is unacceptably long.

You’ve made your case that your company could significantly improve their business performance and you could do your job better if SEM imaging and analysis were easier, faster and more accessible. Can a desktop SEM do what you need? This article provides the answers and helps you to select the right SEM.

EDX analysis with a scanning electron microscope (SEM): how does it work?

By Antonis Nanakoudis - Jun 21, 2018

Scanning electron microscopes (SEMs) employ electron beams in order to get information from a sample at the nanoscale. The main type of signals that are detected are the backscattered (BSE) and secondary electrons (SE), which generate a grayscale image of the sample at very high magnifications. However, there are many other signals which can be a product of the electron-matter interaction, and these can provide additional information about the sample. In this blog we will describe how energy-dispersive X-ray (EDX or EDS) analysis works on a SEM.

What is SEM? Scanning electron microscope technology explained

By Antonis Nanakoudis - Jun 7, 2018

Scanning electron microscopy (SEM) has become a powerful and versatile tool for material characterization. This is especially so in recent years, due to the continuous shrinking of the dimension of materials used in various applications. In this blog, we explain what SEM is and describe the main working principles of a SEM instrument.

Battery research with a SEM: inspecting one layer at a time

By Luigi Raspolini - May 31, 2018

Batteries revolutionized the world of electronics by enabling us to carry an energy reserve in our pockets. Miniaturization and efficiency are the two key words when it comes to new developments in this field, impacting with the battery materials’ properties and stretching their limits. Let’s take a look at how researchers characterize materials and gather relevant information about batteries using scanning electron microscopy (SEM).

Additive manufacturing: improving the quality of AM processes through SEM analysis

By Antonis Nanakoudis - May 17, 2018

In a previous blog, we introduced Additive Manufacturing (AM) as a new manufacturing approach and described its key points (you can read the blog here). Additive Manufacturing, also known as 3D printing or rapid prototyping, has attracted the attention of many people and industries around the world due to its unlimited and promising potential. In this blog we will describe how the use of a Scanning Electron Microscope (SEM) can be a powerful tool to monitor and improve the quality of additive manufacturingprocesses.

Effective asbestos detection with a Scanning Electron Microscope (SEM)

By Luigi Raspolini - May 10, 2018

Resistance to fire, sound absorption, tensile strength and low price caused a boost in asbestos mining activities at the beginning of 19th century.

Already used in the production of asphalt, brake pads, electrical insulators, fireproof suits, technical fabrics and other everyday products, asbestos started its golden century when the Austrian engineer Ludwig Hatschek invented the first asbestos-cement, often mistakenly referred to as Eternit.

The material properties, particularly its lightness and resilience, started a real revolution in the construction engineering and asbestos-cements factories, which immediately emerged all over the world.

What is depth of field and how can I optimize it in a scanning electron microscope?

By Luigi Raspolini - May 3, 2018

Imaging with a scanning electron microscope (SEM) consists of taking pictures of small features. So why not consider a comparison with photography? Let’s analyze how similar the behaviors of a SEM and a camera are when it comes to focusing on your subject, and what the exact definition of depth of field is.

How scanning electron microscopy fuels biomedical research

By Dr. Jasmin Zahn - Mar 15, 2018

Biomedical research is a wide field. It describes an area of science devoted to the study of the processes of life, the prevention and treatment of diseases, and the genetic and environmental factors related to diseases and health. And since the field is so diverse, its range of investigation equipment is too. Scanning electron microscopy (SEM) is one of those types of equipment, and is used to describe tissue or organ structures to gain insights into possible alterations and diseases. To show the variety of topics explored with a SEM — demonstrating its power and vast range of applications — this blog will introduce you to three scientific studies.
