circuit board

IXRF Systems’ ATLAS M microEDXRF spectrometer is the latest general purpose micro/small spot energy dispersive X-ray fluorescence (EDXRF) spectrometer for the measurement and mapping of elements from sodium (Na) through uranium (U). Designed to image and analyze a wide variety of sample types, ATLAS leads the industry in virtually every major specification category from the most powerful software and the highest detector active area, to our superior perpendicular geometry and smallest micro-spot.

ATLAS’ Iridium Ultra software platform, developed with SEM/EDS elemental mapping and analytical functionality, is unsurpassed in it’s ability to provide elemental and phase mapping, line scans, critical dimensions (CD) as well as qualitative and quantitative elemental analyses of solids, liquids, particles, powders and thin films. The functional, flexible, and feature-rich software suite guarantees unprecedented productivity. ATLAS M is the microXRF (μEDXRF) elemental analyzer that leads with innovation.

Micro X-ray fluorescence (µXRF, µEDXRF, microXRF, microEDXRF) spectroscopy is an elemental analysis technique that relies on the same principles as X-ray fluorescence (XRF) spectrometry. The difference is that micro x-ray fluorescence (microEDXRF) spectrometry has a spatial resolution with a diameter many orders of magnitude smaller than conventional XRF, WDXRF or EDXRF spectrometers. Practically, microEDXRF spectrometers with high-precision scanning XYZ-stages  — like the ATLAS series —  function as a type of  XRF hyperspectral imaging microscope, where each pixel (in a map or image) contains information from 4 – 40 keV in the electromagnetic spectrum.

While a smaller excitation spot can be achieved by restricting X-ray beam using a pinhole aperture, this method blocks much of the X-ray flux which has an adverse effect on the sensitivity of trace elemental analysis. Modern polycapillary focusing X-ray optics are able to create small focal spots of just a few micrometers in diameter. By using such X-ray optics, the IXRF Systems’ ATLAS series of imaging spectrometers provide a tiny focal spot (down to  5 μm, depending on desired configuration) that is much more intense and allows for enhanced trace element analysis and the creation of hyperspectral images of a sample. Micro X-ray fluorescence (μEDXRF) spectometry is commonly employed in many applications, such as: botany, cement, forensics, small feature evaluations, elemental mapping, mineralogy, metals & alloys, electronics, multi-layered coating analysis, micro-contamination detection, film and plating thickness, biology and environment.*
