Title Materials Science Laboratory Offers Elemental Mapping Solutions to Provide Answers to Questions on the Microstructure Level
Introduction Advanced MicroAnalytical provides elemental mapping and other material testing services to communicate complex information to clients in an efficient and compelling manner.

Salem, NH, January 20th, 2020

Elemental mapping leverages the compositional precision inherent in techniques such as energy dispersive x-ray spectroscopy (EDS) microanalysis and combines it with high resolution imaging to present complex data in an accessible and visually striking format. This makes it possible to communicate complex information in an effective and powerful manner for those seeking answers to material questions at the microstructure level.

It is based on compiling extremely specific elemental composition data across an area of a sample. This is typically done in a scanning electron microscopy (SEM) or transmission electron microscopy (TEM) using EDS analysis. A high resolution image of the area of interest is collected along with the EDS data, and the two are correlated. For every pixel in the digital image collected, a complete elemental spectrum is also collected. By processing these spectra, the relative intensity of spectral features associated with a number of elements of interest can be translated into computed colorization layers, which color codes the electron photomicrograph signifying layers and sites of elemental compositional information in the sample.

This technique allows complex systems of precipitates, minerals, composite materials or laminates to be examined using the chemical information about the materials to create another dimension of insight. With additional processing, not only raw elemental composition can be used in this colorization process, but unique compositional phases can be similarly colored, or the quantitative composition of a given element examined in a false-thermal map mode. The use of elemental mapping techniques can sometimes be the subject of an entire analysis in the laminate, petrographic or ceramics industries.

Putting this scientific resource to work for clients across the globe are the highly experienced staff of dedicated scientists at Advanced MicroAnalytical. They employ these and other advanced techniques to assist clients in highlighting fine features and variations in any complex system present in a sample.
