Dev.)Requirements for compositional analysis varyfrom rough estimates on simple samples toaccurate results from spectra with complexoverlaps. Whatever your application, INCAEnergyhas the power to reliably provide the answer.LIGHT ELEMENTSData from Bastin(750 samples)0.20ALL ELEMENTSData from Heinrich(1400 samples)0.150.100.050.00I XPP matrix correction that works for moresituations than Phi-Rho-Z or ZAF combinedI Automatic correction for the influence ofcoating elementsTIMIZAFBASTIN-PhiRho-ZXPPTIMIZAFBASTIN-PhiRho-ZXPPTests on published data show that XPP results are moreaccurate than older methods, particularly for light elementsThe secret to investigating thespatial distribution of elements inyour sample is to have one mappingprogram which works in everysituation. SmartMap™ is the answer.I The complete spectrum imagedatacube is always collected,with dead time corrected X-raydata saved at every pixel.
Youcan therefore be certain that anydata reconstructed from the cubewill be as accurate as if it wascollected liveI The dwell time of the acquisitioncan be varied to collect data in‘real time’, or as a long singleframe acquisition9 Full quantitative analysisfunctionality for experiencedusers looking for the bestpossible resultI Quant Optimization corrects for beamcurrent changes for un-normalized analysisI Standardize allows real standards to beused where matrix corrections are largeI Profile optimize fine tunes element profilesfor accurate deconvolution of complexpeak overlaps8I Data can be viewed and manipulated at any time, duringand after acquisition- View the data from different elements- Alter the X-ray lines and window widths used- Collect background maps and linescans- Subtract Maps and Linescans9System Basics: SmartMapTMTake advantage of the potential of SmartMap™. The spectrumimage datacube stored during acquisition acts as a virtualsample. All the information needed to perform all thesedifferent types of analysis with the INCAEnergy system is stored11 Seven ways toanalyse yoursample fromone SmartMapacquisitionSystem Basics: Linescan ReconstructionSystem Options: Quantitative LinescanSystem Basics: X-ray MappingSystem Options: QuantMapSystem Basics: Spectrum ReconstructionSystem Options: Phase MapSystem Options: Cameo+1011System Basics: Spectrum ExaminerSystem Basics: Saving, Reportingand Exporting Data12 Spectrum Examiner is a powerful tool that highlightselements present at low levels or in very minor phasesthat can be easily overlooked when X-ray mapping13 INCAEnergy has been designed with data review in mindThis new algorithm finds elements thatwould otherwise be invisible when X-raymapping because:I All collected data is stored in the data tree.Data is stored in project files which allowclear data archiving and easy data transportI The element is present at very lowconcentrationI The element is only present in a minorphase (e.g.
Al in the example below)I Element peaks are overlapped by peaksfrom elements present in higherconcentrationsI Element was not expected to be present inthe sampleUsing Spectrum Examiner means SmartMapTMcan be used to reliably find all the elementspresent in an unknown sample without theneed to collect X-ray spectra first.In the mineral sample shown, As and Al arepresent in minor phases. These elements areclearly highlighted by spectrum examineroverlay.I The results of analysis can be reportedusing the one page report templatesprovided.
A report template editor can beused to create templates to fulfil yourexact requirements. Reports can betransferred to Microsoft® Word at thepress of a buttonX-ray maps for these two elements show howthese elements are concentrated in only smallregions.I Data can be exported in a large number ofwidely used formats including: bitmap, tiff,JPEG, EMSA, and text fileSpectrum examiner appears as blue overlayon top of the sum spectrum.I A full record of an INCA project can bepublished as a websiteI Images, spectra & maps can beautomatically exported into the OlympusSoft Imaging Solutions software packages.As X-ray mapTo share data in INCA format with non INCA users, use thefreeware INCA viewer.Al X-ray map12I The viewer includes many controls for data manipulation,e.g.
spectrum rescalingI System Option: INCA viewer export software is used toexport data in the viewer format13System Options: QuantMapSystem Options: Lines & Grids14 Accurately display chemical variationswhere element peaks overlap16 Beam automation made simple to study linear variations bycollecting data with Lines and Grids softwareQuantMap displays real quantitative chemicalX-ray maps by recalculating SmartMap datato correct for the X-ray background, peakoverlaps and the sample matrixI QuantMaps are created from existingSmartMap data therefore there is no needto choose between traditional X-raymapping and QuantMapping before youstart data acquisition.I In most cases X-ray mapping will correctlydisplay distribution of an element over thesample surface.
However, if there areoverlapping peaks in your sample theelement distribution may be misrepresented.QuantMapping ensures the correctrepresentation of element variation in maps,even where there are peak overlaps.I QuantMap uses INCA's proven quantitativeanalysis algorithms to ensure all elementsare correctly identified and displayed ineach pixel of the spectrum image.Pb QuantMapPb X-ray mapThe example shows Pb X-ray map and a Pb Quantmap for thesame area. The sample also contains significant levels of S,which overlaps with the Pb M line. The Pb X-ray map isshowing the distribution of both Pb and S, whereas the PbQuantmap shows the correct distribution of Pb.System Options: Cameo+TM15 If your eyes could see X-rays, youwould be able to see the compositionalvariations in a sample.I Cameo+ provides this facility by offsetting the X-rayspectrum into the visible range.
This technique providesthe most rapid possible phase information, with phasesalways picked out in the same color.I Take advantage ofincreasedproductivity byusing unattendedcollection tocollect spectrafrom lines andgrids of pointsover a sampleI Plot a quantitativelinescan of thecompositionalvariation alongthe line of pointsSystem Options: SiteLockTM17 As the magnifications used in the SEMincrease, the problems of sample driftbecome more noticeable, smearingmaps and making spectrum collectionfrom small particles difficult.I SiteLock uses the whole electron image tomonitor and correct for driftI Locks even low contrast images and is insensitiveto brightness/contrast changes over timeI Corrects drift during spectra acquisition usingPoint&ID, or SmartMap™14No SiteLockSiteLock Enabled15System Options: Phase MapSystem Options: AutoMate+18 Phase Map provides a convenientmethod for mapping the distributionof phases in a sample.21 One route to increased productivity is to use automationto collect data, leaving you more time to concentrate ondata interpretationI Extracts information from a SmartMapdatacube, during or after acquisitionI Separates phases even when peaks areoverlapped (e.g.
when working at low kV)I Works on all sizes of datacubes. Longacquisition times are not requiredI Chemical information is provided by areconstructed spectrum for each phaseAutoMate+ provides a dedicated navigatorfor setup of automated runs, whether simpleor complex.System Options: Spectrum Synthesis19 Spectrum Synthesis calculates EDSspectra based on parametersselected by the analyst.Using this tool microanalysis experiments canbe planned and optimized, before the sampleis even prepared.
