Thin sections measurements(64-bit OS)

Trace elements in garent Thin section of a garent containing slateFull area map shows symmetric Mn core within the crystalsSelected garnet neasured extensively with strong primary filter to reduce background and to avoid Bragg diffraction peaks370 pixel×460 pixel→170000 pixel mapMeasurement time:1 s/pixelSteps:25μm

SummaryUnique speed and perfoimance in the determination of the element distribution in large sample with measurement tiomes per pixel of 0.3 ms and up tp 4 Million pixels in a single Hyper MapHigh spatial resolution down to 25 μm X-ray spot size,motors steps of 4 μmOptimal for the analysis of inhomogeneous samples,due to better identification of the representative location of interestNon-destructive,fast analysis of large samples without preparation,including solid,power oe liquid samplesQualitative and quantitative analysis of all elements from Na upwards,due to vacuum chamber,detection limit for heavy trace elements in the low ppm rangeStandardless Fundamental Parameter quantification with type calibration optionPowerful Software with multiple tools for optimal data mining
