X-ray Fluorescence (XRF) Microscopy
Also known as microXRF, X-ray Fluorescence Microscopy is a powerful spatially-resolved elemental mapping and chemical microanalysis technique. Under x-ray illumination, samples produce characteristic x-rays that can be analyzed to determine composition.
MicroXRF advantages include:
- Higher sensitivity (in comparison to electron-based techniques such as microprobes)
- Non-destructive for in situ or in operando analysis of elemental migration
- Simultaneous detection of multiple elements and no sample preparation required
Sigray’s AttoMap microXRF systems come in two types: the ambient AttoMap-200 with ultralarge stage travel and the vacuum AttoMap-310 with a goniometer stage for variable x-ray angles of incidence.
