Atlas Apex, the Next-Generation MicroXRF. Today
IXRF Systems is proud to announce the launch of the Atlas Apex M and Atlas Apex X microXRF spectrometers — our most advanced instruments yet, setting a new benchmark for resolution, sensitivity, and automation in elemental analysis.
With over two decades of innovation in X-ray fluorescence technology, we’ve reimagined what’s possible in lab-based microanalysis. The Atlas Apex is engineered for researchers and industrial professionals who demand both flexibility and uncompromising performance.
Breakthrough Features
-
Quick-Disconnect Source Mounting (QDS): Rapidly exchange primary X-ray sources without losing alignment — choose between high-resolution 5 µm optics or high-flux sources up to 40 µm for maximum throughput.
-
Unmatched Sensitivity: Up to four silicon drift detectors (260 mm² active area) deliver higher count rates, faster mapping, and lower detection limits than ever before.
-
High-Resolution Mapping: True perpendicular beam geometry and optics down to 5 µm enable distortion-free imaging of complex microstructures.
-
Enhanced Vacuum Capability: Operating below 0.1 kPa, the Atlas Apex delivers superior detection of light elements from carbon upward.
-
Largest Sample Capacity in Its Class: Analyze specimens up to 7 kg, with mapping areas of 220 x 200 mm (M) and 400 x 300 mm (X).
Figure 2. MicroXRF elemental map collected by the U.S. Geological Survey (USGS) in Spokane from a rare earth element (REE)–rich carbonatite dike genetically associated with the world-class Mountain Pass REE deposit in California. The map highlights calcite (blue), altered barite (gray), and REE-bearing carbonate minerals bastnäsite and parisite (white and pink). These minerals are the primary hosts for critical rare earth elements including La, Ce, Pr, and Nd. The map beautifully reveals intra-crystal zoning between bastnäsite and parisite, tied to variations in Ca and Nd content—insights that are vital for understanding REE mineralization, U-Pb geochronology, and the geologic evolution of carbonatite-hosted deposits. This work underscores the value of microXRF for critical minerals research, rare earth element geology, and resource characterization.

These pedogenic nodules illustrate how geological and soil processes concentrate critical minerals and rare earth elements through redox-driven reactions. Such high-resolution elemental imaging highlights the role of microXRF in geology, geochemistry, and critical mineral research.

Figure 5. MicroXRF elemental map of a sea cucumber (holothurian) fossil from the Mazon Creek Lagerstätte in Illinois. Conducted in collaboration with Professor Roy Plotnick and the University of Illinois Chicago Paleontology group, this analysis highlights how ironstone concretions preserve exceptional Carboniferous marine fossils. Elemental imaging reveals the distribution of calcium (Ca), iron (Fe), sulfur (S), and even arsenic (As), providing new insight into fossil preservation, critical mineral cycling, and rare earth element geochemistry. This study demonstrates the power of microXRF for paleontology and geology research.
