Atlas Apex
MicroXRF Series
Non-destructive elemental mapping down to a 5 µm spot, for research and industrial laboratories.
Atlas Apex is a microXRF spectrometer that maps elemental composition — from carbon through uranium — without damaging the sample. A perpendicular X-ray geometry keeps the beam accurate at the microscale, and detector configurations scale up for faster, more sensitive analysis as your work demands it.
The series comes in two chamber sizes: Atlas Apex X, built for large or long samples, and Atlas Apex M, a compact benchtop platform — both sharing the same optical engine and Iridium Ultra software.

Atlas Apex X vs.
Atlas Apex M
Same 5 µm optical engine and Iridium Ultra software in both — the real difference is chamber size and how much sample you need to cover.
Benchtop
Atlas Apex M
A compact benchtop microXRF spectrometer built for the same 5 µm resolution and perpendicular geometry, in a smaller footprint.

Largest Chamber
Atlas Apex X
The industry's most voluminous sample chamber — built for automation of more samples, larger-area mapping, and wider variability of sample types.
- Sample chamber
- 940 × 660 × 355 mm
- Mapping area
- 400 × 300 mm
- Best fit
- Long core, large parts, wafers
- Edge-to-edge mapping of 300 mm wafers
- Fewer setups for long, intact sample runs
- Widest variability of sample types and sizes

What Makes Atlas Apex Different from Conventional µXRF
Not marketing claims — the specific geometry, detector, and vacuum choices that set the resolution and sensitivity ceiling.
Perpendicular Geometry
The X-ray source is normal to the sample, producing a true circular spot down to 5 µm with no elliptical distortion. Angled-geometry competitors are limited to a 25 µm minimum spot because of beam ellipsing.

Up to Four SDD Detectors
Bundle up to four Silicon Drift Detectors for a combined active area of 260 mm², boosting throughput, sensitivity, and trace-element detection limits without compromising resolution.

Full Spectrum, Every Pixel
Every mapped pixel stores a complete XRF spectrum. Users can generate new elemental maps, extract spectra, or re-quantify data after acquisition — without rescanning the sample.
Enhanced Vacuum Capability
Sealed chamber with adjustable vacuum pressure (<0.1 kPa) significantly boosts sensitivity for low atomic number elements, extending detection down to sodium — and carbon on the LE configuration.
“Atlas Apex microXRF delivers ~10 µm pixel resolution, revealing fine-grained mineral phases and chemical zoning that remain hidden at coarser resolutions, approaching the detail of synchrotron-based mapping.”

Atlas Apex Across Geology, Life Science, and Industry
From ore deportment to plant metal homeostasis to PCB failure analysis — real Atlas Apex output, not renders.
Ore Mineralogy and Deportment
A sphalerite-bearing ore sample from the Philipsburg mining district shows a quartz vein in dolomitic carbonate host rock, with secondary Fe and Cu minerals from weathering. At pixel sizes under 20 microns, the finely intergrown nature of secondary minerals — and the polymetallic association of Cu, Fe, As, and Zn — becomes visible in ways bulk assay alone cannot show.
In gold deportment work specifically, Atlas Apex maps how gold relates to pyrite, arsenopyrite, arsenic, and sulfur — helping metallurgists understand whether gold is likely free, attached to other minerals, or locked within sulfide phases.

Phytomining and Plant Metal Homeostasis
Atlas enabled high-resolution elemental mapping of selenium across whole plant structures of Neptunia amplexicaulis, revealing tissue-specific hyperaccumulation patterns that support hypotheses on phloem-mediated selenium redistribution and taproot storage.
The same technique applies across botany more broadly — from heavy-metal to REE hyperaccumulation studies, entirely non-destructive, with no coating or sample prep required.

Microelectronics: Assembly to Defect
Atlas Apex connects broad-area elemental screening with micron-scale investigation on one platform — mapping material composition across boards, components, traces, and complex assemblies, then targeting anomalous features with high-resolution sub-maps.
5 µm mapping resolves fine interconnects; K/Ca overlays localize packaging residues and particles; Ag/Au overlays spatially resolve wire-bond and frame connections — all without sectioning the device.

Battery Electrodes and Energy Storage
MicroXRF maps can reveal variations in electrode coating, current-collector defects, contamination, and transition-metal crossover between cell components. Depending on chemistry, elements of interest may include nickel, cobalt, manganese, iron, aluminum, phosphorus, sulfur, and copper.
