Prospectives for μ-XRF
μ-XRF is a relatively new analytical method with a high analytical potential. In between the third instrument generation is available and most of the components have already a high performance. But still there...

XRF-Basics
This chapter describes the main interactions of X-rays with matter and how these can be used for the characterization of material. Such interactions are absorption, emission of fluorescence (or secondary) radi...

Sample Preparation
XRF very often is marked as a non-destructive analytical method. But this is wrong. The sample often has to be cut to fit into the instrument, it has to be crushed and grinded to make it homogeneous or it has ...

Main Components of X-ray Spectrometers
This chapter discusses the main components of a XRF spectrometer oriented but not limited for μ-XRF. For the excitation the different possibilities for excitation—by electrons are photons—are compared and the ...

Chapter
Quantification
For quantification in μ-XRF special conditions has to be taken into account because the analyzed material typically is non-homogeneous—in the sample surface or normal to that, i.e. the sample has a layered str...

Relations to Other Analytical Methods
There are several other analytical methods available that allow the determination of elemental or structural composition—also as micro-analytical methods for small sample volumes. The detailed discussion of μ-...

Special Requirements for μ-XRF
This chapter starts with a short overview for the development of instrumentation for position sensitive X-ray analysis. Then the different possibilities for a position sensitive measurement are introduced and ...

Chapter
Applications
Because μ-XRF is still a relatively new method, continuously new applications are developed. The method is already used for a wide range of different purposes but its high flexibility offers continuously the p...

Recycling of orogenic arc crust triggers porphyry Cu mineralization in Kerman Cenozoic arc rocks, southeastern Iran
Pre-collisional Eocene–Oligocene arc diorites, quartzdiorites, granodiorites, and volcanic equivalents in the Kerman arc segment in central Iran lack porphyry Cu mineralization and ore deposits, whereas collis...

Nondestructive characterization of nanoscale layered samples
Multilayered samples consisting of Al, Co and Ni nanolayers were produced by MBE and characterized nondestructively by means of SRXRF, μ-XRF, WDXRF, RBS, XRR, and destructively with SIMS. The main aims were to...

First X-ray fluorescence excited Kossel diffraction in SEM
We present, for the first time, X-ray fluorescence excited Kossel patterns in the scanning electron microscope by way of a compact X-ray tube and a focusing polycapillary lens. Both the diffraction geometry in...

Tectonics, Climate, and Landscape Evolution of the Southern Central Andes: the Argentine Puna Plateau and Adjacent Regions between 22 and 30°S
The history of the Puna Plateau and its marginal basins and ranges in the Eastern Cordillera and the northern Sierras Pampeanas structural provinces in northwestern Argentina impressively documents the effects...

Central and Southern Andean Tectonic Evolution Inferred from Arc Magmatism
Patterns of spatial distribution, and geochemical and isotopic evolution from subduction-related igneous rocks provide tools for scaling, balancing and predicting orogenic processes and mechanisms. We discuss ...

Links between Mountain Uplift, Climate, and Surface Processes in the Southern Patagonian Andes
Miocene surface uplift of the southern Patagonian Andes, related to an episode of rapid plate convergence prior to the ∼14–10 Ma collision of the Chile Ridge with the South American subduction zone, has produc...

Examination of the Excitation Performance of Different Capillary Optics
The use of X-ray optics allows for elemental analysis of small samples and small areas: particles, inclusions and elemental distributions. Previously, collimators have been used to limit the X-ray beam diamet...
