Overview
The Thermo Fisher ARL QUANT’X Energy Dispersive X-Ray Fluorescence (EDXRF) Spectrometer is an engineered analytical platform designed for precise, multi-element quantitative analysis across solid, powdered, liquid, and thin-film samples. Based on the fundamental principle of X-ray fluorescence—where primary X-rays excite atoms in a sample, causing emission of characteristic secondary (fluorescent) X-rays—the ARL QUANT’X delivers rapid, non-destructive elemental composition data without requiring matrix-matched standards. Its optimized optical geometry, high-flux microfocus X-ray tube, and low-noise SDD detector collectively enable high spectral throughput and exceptional peak-to-background ratios. This architecture supports trace-level detection while maintaining robust performance across major, minor, and ultra-trace concentration ranges—making it suitable for routine QC, regulatory compliance testing, and method development in regulated and non-regulated environments.
Key Features
- Simultaneous quantification of elements from fluorine (F) to uranium (U) in a single measurement cycle
- Wide dynamic quantification range: sub-ppm (<1 ppm) to 100% mass fraction, validated per ISO 22036 and ASTM E1621
- Measurement times adjustable between 10–60 seconds per sample, configurable by element and required precision
- Variable collimated X-ray beam with motorized aperture selection (1–15 mm diameter) for optimal excitation area matching
- Integrated CCD camera for real-time sample imaging and precise positioning—critical for heterogeneous or patterned samples
- Peltier-cooled silicon drift detector (SDD) with energy resolution ≤140 eV at Mn Kα, enabling reliable separation of overlapping peaks (e.g., S Kα/Pb Mα, Cr Kβ/Mn Kα)
- UniQuant™ proprietary fundamental parameters algorithm—enabling accurate standardless quantification without prior calibration curves
- Modular sample handling: compatible with autosamplers, cup holders, film stages, and custom fixtures for powders, pellets, filters, and coated substrates
- Intelligent thermal management system with adaptive fan control—reducing acoustic noise and stabilizing detector temperature within ±0.1 °C
- Rugged mechanical design certified for continuous operation (>8,000 h MTBF), including vibration-damped optics mount and sealed analysis chamber
Sample Compatibility & Compliance
The ARL QUANT’X accommodates bulk solids (metals, ores, ceramics), pressed pellets, loose powders, slurries, thin films, electroplated layers, and homogenous liquids—all without digestion or dilution. Its vacuum and helium purge options extend light-element sensitivity down to F and Na. The instrument complies with IEC 61000-6-3 (EMC), IEC 61000-6-4 (emissions), and EN 61010-1 (safety). Software workflows support audit trails, electronic signatures, and 21 CFR Part 11–compliant user access controls when configured with TRACEcom™ LIMS interface. Method validation documentation aligns with ISO/IEC 17025 requirements for accredited testing laboratories.
Software & Data Management
ARL QUANT’X operates with Thermo Scientific™ QUANT-X software—a modular suite supporting method creation, spectral evaluation, layer-thickness modeling (ISO 3497), and statistical process control (SPC). All spectra are stored in vendor-neutral .rxf format; raw counts, peak deconvolution parameters, and uncertainty estimates are fully exportable. TRACEcom™ enables bidirectional communication with laboratory information management systems (LIMS), automating sample registration, result transfer, and report generation. Custom scripting (via Python API) allows integration into automated QA/QC pipelines. Multi-language UI (English, German, French, Spanish, Chinese, Japanese) ensures global deployment readiness.

FAQ
Does the ARL QUANT’X require external cooling water or liquid nitrogen?
No—it uses a thermoelectrically cooled SDD detector with no cryogenic consumables.
Can it analyze light elements such as sodium or oxygen?
Yes, when operated under vacuum or helium purge mode, with appropriate calibration and matrix correction.
Is UniQuant suitable for unknown or complex matrices?
Yes—UniQuant employs physics-based fundamental parameter calculations and iteratively refines absorption/enhancement corrections using measured intensities.
How is measurement reproducibility verified?
The system includes built-in drift monitoring via reference foil checks and supports daily/weekly performance qualification per ISO 8258 (Shewhart control charts).
What maintenance is required beyond routine cleaning?
Annual preventive maintenance includes X-ray tube output verification, detector resolution calibration, and optical alignment validation—documented in service reports compliant with GLP/GMP expectations.
