Live Elemental Mapping

ChemiSEM & ChemiPHASE

Thermo Fisher Scientific

Instant Elemental Mapping

See chemical compositions live as you image with real-time, color-coded elemental overlays.

Precise Phase Identification

Phase mapping with pixel-level accuracy provides clear, color-coded identification of distinct material phases.

Smart Spectral
Fitting

Advanced algorithms handle peak overlaps and artifacts to ensure your results are always accurate.

ChemiSEM uses a combination of machine learning and ultrafast signal processing to provide elemental maps in real time over a live SEM image. Background quantification of the signals provides a live map of the sample’s composition, displaying a live image of pixel-by-pixel elemental analyses simultaneously. This makes elemental analysis more accessible and faster than ever before.

ChemiSEM is a software capability that merges high resolution SEM imaging with real time elemental analysis EDS. This complete integration means that as you capture detailed SEM images, you simultaneously gain instant access to the elemental composition of your sample. Switching between different software interfaces is unnecessary – ChemiSEM brings everything together in one intuitive interface with a single click. With Phenom Desktop SEMs, the X-ray signals generated by the sample interacting with the electron beam are continuously collected and overlayed with the backscattered electron signals, creating a color-coded overlay of elemental information that provides clear, immediate visualizations of the chemical makeup of your samples.

This SEM/EDS integration simplifies comprehensive analysis workflows, making it easy to identify any regions of interest, detect contaminants or impurities, or simply understand the elemental distribution within your samples quickly.

ChemiSEM & ChemiPHASE

Product Features

Live Elemental Mapping

Real-Time Data

Data is automatically organized within a project by associating each EDS collection with an image. Easily add and remove new images and EDS analyses within your open project.

Clear Visualization

Distinct color-coded overlays on SEM images highlight the elemental distribution of your samples, simplifying the identification of regions of interest or contaminants.

Integrated Functionality in the Phenom UI

Ease of Use

Access live SEM imaging and EDS functions on the same screen. This integration is easy to navigate and operate with a standard mouse, where ChemiSEM can be accessed with a single click. Detected elements can be selected or deselected at the bottom of the screen, and users have several options in addition to this feature here: see EDS count rates, change the level of coloration to observe BSD/EDS simultaneously, include or exclude elements using a periodic table, or use a spot analysis based on weight or atomic percentage.

Advanced Data Processing

Accurate Analysis

Common artifacts like sum and escape peaks, in addition to peak overlaps, are handled effectively via ChemiSEM software based on machine learning and ultrafast signal processing.

ChemiPHASE

ChemiPhase: Pinpoint Material Phases

ChemiPhase (phase mapping) involves the use of elemental data to identify and differentiate distinct phases within a sample. Unlike standard EDS mapping, which simply displays the distribution of individual elements, phase mapping clusters regions with similar elemental compositions into distinct groups. This process allows for a more comprehensive understanding of the sample’s microstructure by highlighting areas that share similar elemental percentages, thus identifying different phases and providing insights into the material’s properties and behavior.

Discrete Phase Segmentation

Clear-Cut Edges

ChemiPhase breaks the sample into segments, assigning each a unique color based on its elemental composition. This results in discrete edges that distinctly separate one phase from another.

Consistent Elemental Distribution:

Each identified phase consists of regions with statistically similar elemental makeup, providing a clear and binary representation of the sample’s composition.

Single Pixel Identification

Avoid Peak Overlaps:

ChemiPhase can distinguish between different material phases on a pixel-by-pixel basis, even in cases where elemental peaks overlap. This ensures that each phase is accurately identified without interference from neighboring elements.

Detailed Phase Mapping:

Perfect for complex samples like geological materials or inclusions, ChemiPhase allows for precise phase identification and mapping, providing clear insight into a sample.
