With the advances in energy dispersive spectrometry (EDS) detectors, the technology has moved from single point-and-shoot spectrum collection to complete X-ray imaging. In times past the output of the data collection was simply an image but modern systems have a full spectrum associated with each individual pixel in the image. This allows us to do a significant amount of post processing of both the spectra and images to bring out the details, correlate elemental distributions, and locate small contributions not easily visible in the sum spectra.
In this webinar we will be taking a look at how different microscope settings affect map output and quality under high vacuum and variable pressure conditions and what information can be gained by varying these settings. Based on several examples, we will go through the various map types that can be calculated based on the raw data and discuss the difference between them. We will also cover some of the various options for extracting data from the maps in order to access information that is not obvious or accessible at first glance.
If you attend this webinar you will:
- Gain insight into the experimental parameters to consider when optimizing the SEM for EDS mapping.
- Learn about the strengths and weaknesses of the different ways of visualizing elemental distributions in a sample.
- Get the most out of your data collection by knowing the post-processing tools available.

Quantification And EDS: From Spectrum To Composition
What: During this webinar we will look at some of the fundamentals of the EDS technique, which assumptions and corrections are made in order to go from spectrum to composition, and what settings and parameters we can adjust to increase reliability and repeatability of the measurements. Our starting point will be the ZAF standard less quantification but we will also take a look at peak to background based models and the benefits of quantification with standards and normalized versus non-normalized quantification.

Transmission EBSD - Taking Transparency to a New Level
What: Transmission EBSD or TKD has become a fascinating way of doing orientation analysis on electron transparent samples using a standard EBSD system. This analysis approach allows ultra high resolution and can also be used to complement other analytical techniques for characterization of nanomaterials. In this webinar the fundamentals, capabilities and future potential will be discussed.

Advances in X-ray Elemental and Phase Mapping
What: True EDS spectrum phase mapping is a complex data analysis routine based on the chemistry of the actual spectrum and is much more than an image analysis or image correlation routine. Traditional elemental mapping uses x-ray signal intensity to understand elemental variations within a material for each element individually. Basic comparisons of elemental combinations with x-ray maps are possible with image correlation and comparison, both manually and automatically. However, direct spectrum phase mapping evaluates the material for all elements and makes complex associations of elements together. The result is a full qualitative and quantitative materials characterization in one phase map image. In this session we will learn about the TEAM™ EDS direct data phase approach, as well as what can be done with this data to maximize insight into the compound chemistry of a sample.
