EDS analysis (energy-dispersive X-ray spectroscopy, also known as EDX analysis) is a powerful technique for the study of micro-scale chemical composition. Combined with scanning electron microscopy (SEM), EDS derives compositional information from the X-rays that are emitted when the electron beam scans over a sample. The range of elements that can be detected spans almost the entire periodic table, and the data provided by EDS is essential for a range of applications, from process/quality control to failure analysis and fundamental research. As a result, almost every SEM is equipped with an EDS system.

Thermo Scientific ColorSEM Technology revolutionized EDS analysis, providing you with elemental information much more quickly and easily than traditional third-party solutions. Fully integrated within the user interface of the SEM, elemental information is displayed as color in the live image, meaning that SEM is no longer a greyscale technique. ColorSEM Technology is based on live quantification and builds on decades of our expertise in EDS analysis, guaranteeing reliable results. Since ColorSEM Technology is always on, it doesn’t just dramatically shorten your time to results. It also shows features that would have previously gone unnoticed, giving you more complete information.

Benefits of EDS analysis with ColorSEM Technology

Complete information - ColorSEM Technology provides the most comprehensive micro-scale elemental composition possible. Immediate color results allow researchers to see the big picture, revealing defects or imperfections they might have otherwise missed.

Always on - Integrated color imaging and elemental analysis means researchers no longer need to move from SEM imaging to EDS analysis for each sample, thereby decreasing the time spent developing color images.

Increased productivity - For quick screening of composition, ColorSEM Technology gives you access to elemental information 2-4 times faster than conventional techniques.

Broader userbase - With exceptional ease of use and immediate color results, ColorSEM Technology makes elemental information accessible to everyone. Multi-user labs can readily increase the number of scientists or engineers who can use their facilities.

 

ColorSEM Technology is always on and enables any user to acquire elemental data – you’ll have more access to complete information than ever before. See just a few examples of the utility of simultaneous EDS and SEM analysis with the videos below.

Elemental information in the blink of an eye

This video is taken on the Thermo Scientific Prisma E SEM equipped with a 30 mm2 EDS detector. We demonstrate the speed of ColorSEM Technology with composition automatically identified (AutoID) and easy selection of elements of interest.

Highlight contrast that would otherwise go unnoticed

ColorSEM Technology is always on – you no longer have to switch applications when you need elemental information; instead live results are shown in the SEM user interface. This video highlights several forms of elemental information (point and area).

Reliable results

Elemental information is useless when it is not reliable. This video shows how ColorSEM Technology is capable of dealing with X-ray peak overlap and deconvolution – making sure that your elemental information is correct and relevant, even in live color imaging.

See how ColorSEM Technology enables you to see the most complete sample information and detect defects or imperfections you might have previously missed. Also, discover how it gives you access to elemental information 2-4 times faster than conventional techniques.
