EDS & XRF for Electron Microscopy

IXRF - Model SEM/EDS and SEM/EDX - Energy Dispersive X-ray Spectroscopy for Scanning Electron Microscopes

Energy-dispersive spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of an electron beam (e^– beam) and a sample within a Scanning Electron Microscope (SEM) instrument. Its characterization capabilities are due in large part to the fundamental principle that each element has a unique atomic structure allowing a unique set of peaks on its electromagnetic emission spectrum (which is the main principle of spectroscopy). The peak positions are predicted by the Moseley’s law with accuracy much better than experimental resolution of a typical SEM/EDS or SEM/EDX instrumentation.

Model SEM-XRF - X-ray Sources for Electron Microscopy (SEM)

microXRF X-ray sources for Scanning Electron Microscopes (SEM): addition of an polycapillary X-ray tube and Iridium Ultra software will transform your SEM’s quantitative analytical capabilities. Higher peak to background ratios enable greater elemental sensitivity for higher Z elements: sensitivity exceeding e–-beam excitation by a factor of 10-1000X. Exceptional beam stability, together with a modern SDD X-ray detector, afford higher precision with ppm-level sensitivity. Non-conductive materials may be analyzed without any special preparation or coating. We integrate with your SEM to deliver full spectrum analysis using excitation from both the e–-beam and our X-ray source.

IXRF - Model SDD - Silicon Drift Detectors

IXRF’s range of electronically cooled (LN2 free) Silicon Drift Detectors (SDD) are optimized when coupled with our innovative Ethernet based 550i digital pulse processor. Specifically configured to each customer`s scanning electron microscope (SEM), IXRF`s SDD detectors provide exceptional and stable performance over a wide range of input count rates to produce rapid X-ray fluorescence elemental maps. The SDD detector is available in both EDS (SEM mounted with slide assembly) and XRF (various designs, no slide) formats. Choices of window materials are available, from Beryllium (8µm) to Thin Polymer (for light element x-ray transmission) and sensor active areas of 10mm² to 100mm² are offered. In addition, all or our SEM SDD versions are vibration free.
