• Automatic Peak Identification Using rule-based identification and peakshape deconvolution, elemental peaks are automatically identified quickly andaccurately.

• Confirm Elements PresentSpectraCheck both visually and statisticallyconfirms the presence of an element usingspectrum simulation and comparison routines to provide both an overlappedspectrum, and a chi-squared value indicating goodness of fit.

• Accurate Peak Intensities Elemental peak references provide a complete set of spectral peak shapes collected with a typical EDS system. Theintensities from these shapes are auto-matically corrected to match the detectoron your microscope, eliminating the needto periodically calibrate the system withstandards.

• Precise Matrix Correction Since 1983 Thermo Scientific X-ray analyzers have been using the PROZAPhi-Rho-Z matrix correction algorithm asimplemented by Bastin et al. This modelof Phi-Rho-Z has been shown to havesuperior performance to all other methodsof matrix correction.

In addition, processing algorithms and electronics pioneered by Thermo Scientific in 1992 andcontinually developed since then to producespectrum with no peak shift or peak broad-ening, from minimum to maximum count rates.

Point & ShootPoint & Shoot mode integrates electronimaging and X-ray analysis. A single mouseclick provides both elemental identificationand quantitative analysis of the selectedareas of interest of the sample.

Areas on the sample are defined usingpoints, rectangles, circles, polygon or with amagic wand tool. The magic wand tool allowsyou to easily and instantly outline complexareas without having to manually draw aborder. The selection, based on gray levels,is made automatically with just one click.The selected areas may be analyzed instantlyor multiple areas may be selected for automated analysis. Point & Shoot performsprocessing according to your settings. WithPoint & Shoot everything you need is in oneplace. From qualitative to quantitativeanalysis with full standards, Point & Shootis the easiest place to get the spectralresults you need.

Getting to the answer quickly and accurately is critical in today’smicroscopy laboratory. Often you must answer the question of “What is the composition at one or more areas of the sample?”

Multiple spectral processing and analysis steps are performed automaticallyas part of the acquisition

X-ray Microanalysis

Spectral Imaging provides for the display ofany number of element maps, both duringand after the acquisition. It includes a richset of data extraction and analysis functionsfor interpreting the data.

Many methods exist to select spectrafor analysis from a Spectral Imaging dataset –in fact the only limit is your imagination.Because every spectrum from the dataset is fully deadtime corrected during the acquisition, each spectrum can be used forstandardless or full standards quantitativeanalysis. A single button selection changesthe display from a summed spectrum to amaximal spectrum.

Spectral Imaging Data Extraction Tools: • Rectangle• Magic Wand, a unique tool that allows

the selection of areas by gray levels• Circle• Polygon, for freehand drawn areas• Linescans, with variable number of points

and width

Spectral Imaging X-ray MicroanalysisSpectral Imaging has revolutionized x-ray mapping. With a spectrumacquired at every point it is the centerpiece for all imaging, X-ray mapping,Linescan and advanced automated analysis. With one click, the NORANSystem 7 collects data that can be analyzed repeatedly without the needfor re-acquiring or changing acquisition parameters. Once the data is collected, you may choose to analyze it locally at the microscope or takethe data offline to a different computer for report preparation.

Network-Ready Data AnalysisFrom its inception, the NORAN System 7 was designed for theeasy transfer of information over a data network. This allowsthe microscopist to analyze data away from the lab.

Projects are stored as folders in Windows® Explorer®,which groups the analyses of samples or sample sets for easyretrieval. NORAN System 7 software can be installed on multiplecomputers using the site license included with every system.Projects can then be conveniently accessed and analyzed fromyour office or any other compatible computer within the facility.Data can also be situated on a Windows Server System™

allowing for backup and support by your local IT group.

The spectral imaging data cube contains an electron image and a spectrum at every point.

Difficult to interpret sample compositions can nowbe identified effortlessly with the Noran System 7exclusive automatic quantitative mapping. Goingfar beyond simple X-ray maps, Noran System 7sets a new standard in sample analysis. With justone click difficult-to-interpret X-ray maps are transformed into clear elemental maps withoutpeak overlaps or background effects. This fullquantitative analysis is done effortlessly, yet usesthe power of least squares fitting to provide results you will have confidence in every time.

The example shown here displays gross countand weight % maps. When basic X-ray mapping isused, the gross count maps all appear the samedue to peak overlaps between Si, Ta and W. It isonly with the application of full quantitative analysisthat the spatial separation becomes evident. Hadonly basic X-ray mapping been used, an accurateinterpretation of the composition could not bedetermined.

Only the NORAN System 7 produces full quantitative analysisfrom every point in your sample

Traditional X-ray microanalysis systemsallow each microscopist to choose the elements for analysis. This can lead to different results form the same sample,depending on who performed the analysis.Have you ever wondered how you could getall of the people in the lab to perform thesame analysis and obtain the consistentresults? COMPASS software is the answer.This additional software tool for use withNORAN System 7 uses powerful multivariatestatistical algorithms as created by PaulKotula et al. and licensed from Sandia

National Labs. COMPASS allows, with asingle click of a button, the automatic andcomplete analysis of a Spectral Imagingdataset.

The results from COMPASS consist of aset of spectrum and component imagesshowing the spatial distribution of the component within the sample. COMPASS isthe ideal tool for anyone wishing to auto-matically analyze spectral images or X-raymaps. Since COMPASS algorithms arelargely free of user input, everyone gets thesame answer, the CORRECT answer.

Xphase Compositional Distribution Mapping Software

Dual Detector OperationThe NORAN System 7 allows up to two detectors to be attached to a single analyzersystem. Data can be collected in any acquisition mode selecting a single detector orby selecting both detectors. Dual detector operation gives you more than 2,000,000counts per second processing capability. Configurations may include deployment oftwo Si(Li) detectors, two SDD units, or one Si(Li) and one SDD combination.

While analysis using COMPASS is the ultimate in automatic, hands-free SpectralImaging analysis, our Xphase softwaregives you the option to take full control ofthe results.

Xphase software uses any set ofimages of the sample – whether they areraw maps, quantitative maps or COMPASSdistribution images – and calculates whichareas of the sample have nearly the samecomposition. It then creates a binary imagefor the each area. Spectra representingeach of the resultant phases is extractedfrom the Spectral Imaging data cube byusing the binary images as a mask. Theresult is that with little effort you determinewhich areas of the sample have the samecomposition, and then generate images andspectra representing those areas.

• Pulse Processor Rate – Dynamicallyadjusts the analyzer to the conditions of the microscope. Simply adjust themicroscope for the optimum image andNORAN System 7 adjusts accordingly.

• Peak Suppression – The Zero Peak is auseful diagnostic tool. When it is notneeded, NORAN System 7 removes itfrom view so you can concentrate on theelemental data.

• High keV Cutoff – NORAN System 7only acquires the data that is necessaryeconomizing on storage space and processing speed.

• Acquisition Time – Acquisition timesbased on statistics, rather than fixedtime, ensure that the data collected issignificant.

• Brightness/Contrast – There is no needto fine tune the image brightness andcontrast – NORAN System 7 does it for you.

• Drift Compensation Time – Optimizesthe time between compensation cyclesimproving data throughput.

In traditional X-ray microanalysis systems, managing the optimal acquisition condition is atrial-and-error process. The NORAN System 7 monitors the acquisition and fine tunes the system during operation to ensure that the best data is collected every time an acquisition isstarted. Guesswork and rework are eliminated.
