Every two weeks in 2017, we will launch a new recorded webinar covering topics of importance to the X-ray microanalysis and SEM/EDS community featuring our recently introduced Pathfinder X-ray Microanalysis software and analyzer. Each presentation is designed to address a specific discpline such as metallurgy, organic materials, semiconductors and geological samples.

Analysis of Cell Phone Glass Composite

Cell phone cover glass, also known as surface covers, is an important component in today’s high-tech economy. Hundreds of millions of such items are sold each year. This material is composed of multiple surface layers designed  for scratch resistance and reduced reflections deposited on a special glass treated to increase strength.

To understand if an item has been correctly manufactured or to investigate why an item is not performing as expected it is very useful to visualize its structure at the microscopic level. Scanning Electron Microscopy (SEM) and Energy Dispersive x-ray Spectroscopy (EDS) have the ability to visualize materials down to the nanometer level and to reveal the elemental composition of a material to a resolution of some tens of nanometers.

Working with a petrographic thick section of an igneous rock, this presentation demonstrates the application and value of detailed X-ray phase mapping of very large area (27 mm X 48 mm). In order to calculate the bulk composition of a geological sample, or to interpret how the sample formed, an analyst needs to identify phases and their abundance over an area large enough to get a statistically appropriate representation of the complete sample.

This presentation shows how the multivariate statistical analysis of EDS spectral images enable the accurate identification and abundance determination of phases from very large sample areas in practical timeframes. Practical considerations, such as how much data is necessary to successfully generate phase maps, are also discussed.

Geological Analysis with Pathfinder Software

Geologists using SEM/EDS now have all the tools necessary to understand the elemental and chemical composition of petrographic and mineralogical samples. 

In our webinar we demonstrate how the Alpine configuration of our Pathfinder EDS software uses point or area analysis to qualitfy the geological spectra by weight percent, compound (oxide) percent, or can be normalized to the number of cations. We also show how we match an acquired spectrum against a known spectrum stored in a database.

Analysis of Organic Materials with Pathfinder Software

With advances in microscopy techniques such as low vacuum environmental SEMs and cryo-cooling, we can now study organic and life science materials with SEM/EDS. 

This presentation explores how the Thermo Scientific Pathfinder system reveals answers from sparse elemental distribution analysis, trace element detection and analysis based on gray-scale imaging from elemental regions and items of interest. Principal component analysis and x-ray imaging filters enable a highly effective way to visualize and characterize of these regions.

Managing homogeneous distributions in alloys

Understanding alloys can be one of the most challenging analyses in SEM/EDS. Typical SEM/EDS analysis often produce a homogenous element distribution across the sample, masking important chemical differences. 

Our presentation demonstrates two techniques that successfully extract clear differences in these phases. Image filters can bring out clearly seen distinctions between phases without changing the underlying statistics in the data. Principal component analysis (PCA) algorthms quickly determine the dominate components within the sample that correlate to these phases.
