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

By Marijke Scotuzzi - 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.

Do you have repetitive SEM work? Use automated SEM analysis!

By Ruud Bernsen - Nov 6, 2018

Obtaining images is what it is all about in the microscopy business. While searching for that one particle or defect is part of the job, doing this for hundreds of particles or samples is time-consuming work and might not be very challenging. So why not automate your SEM analysis?

How sample preparation for SEM helps lab operators produce images faster

By Karl Kersten - Nov 1, 2018

As a seasoned lab operator, you work with microscopes for the majority of the day, and are very specialized in sample preparation and handling the SEM system. And it’s a responsible job: your output leads to the overall improvement of your company’s products and company results. Therefore, the quality of your work must be outstanding. But at the same time, you want to deliver output quickly.

Using a SEM in packaging material development and analysis

By Luigi Raspolini - Oct 25, 2018

Nowadays, the packaging industry is one of the fastest growing in terms of technology advancement and employing the latest available scientific developments. The reason lies in the greater demand for products and the upscale of shipments from regional transport to worldwide delivery. To ensure that the technologies are integrated in the right way, and to verify the quality of such introductions, more advanced inspection tools are required and scanning electron microscopes (SEM) play an increasingly important role in the material development. This blog will highlight some of the most common uses of electron microscopy within this field of application.

SEM automation guidelines for small script development: simulation and reporting

By Wouter Arts - Oct 18, 2018

Scripts are small automated software tools that can help a scanning electron microscope (SEM) user work more efficiently. In my previous blogs, I have explained how we can use the Phenom SEM with the Phenom programmable interface (PPI) to automate the process of acquiring, analyzing and evaluating images. In this blog, I will add the Phenom PPI simulator to that and explain how you can generate and export reports using PPI.

How SEM helps to detect additive manufacturing defects in a 3D-printed object

By Karl Kersten - Oct 11, 2018

3D printing, or additive manufacturing (AM), refers to processes that are used to make 3D printed objects. In order to achieve this, successive layers of material are formed under computer control to create an object. The objects can have almost any shape or geometry and are produced using digital data from a 3D model or other electronic data source.

But successive layers formed under computer control can result in structural interruptions or defects that negatively affect the reliability of an 3D printed object. And these undesirable defects  should not go undetected; something we discuss in this blog later on. But first, more about 3D printing.
