Malvern PANalytical Axios FAST Wavelength Dispersive X-Ray Fluorescence Spectrometer

Overview

The Malvern PANalytical Axios FAST is a floor-standing, simultaneous multi-channel wavelength dispersive X-ray fluorescence (WDXRF) spectrometer engineered for high-throughput, time-critical elemental analysis in industrial process control and commercial testing laboratories. Unlike sequential or energy-dispersive systems, the Axios FAST employs fixed-channel Bragg diffraction optics—each channel dedicated to a specific element’s characteristic wavelength—enabling true parallel detection of up to 28 elements (from sodium to uranium) in a single, sub-second acquisition. This architecture eliminates scanning delays and delivers exceptional counting statistics, reproducibility, and long-term stability. The system is optimized for routine quantitative analysis across metallurgical, geological, and raw material supply chain applications where precision, repeatability, and operational continuity are non-negotiable. Its robust mechanical design, vacuum-stable optical path, and integrated thermal management ensure consistent performance under continuous 24/7 operation.

Key Features

• Simultaneous multi-element detection: Fixed-channel configuration with up to 28 analyzers enables real-time quantification without spectral overlap or dwell-time trade-offs.
• High-power excitation: SST-mAX X-ray tube with 160 mA current capacity and ZETA technology—actively compensates for tube intensity drift, reducing recalibration frequency and improving long-term accuracy.
• Enhanced light-element sensitivity: Optional HiPer channel with specialized crystal optics and vacuum-purged path for reliable detection of Na, Mg, Al, Si, P, S, and Cl at sub-100 ppm levels.
• Modular goniometer expansion: Supports up to four independent goniometers, each configurable with distinct analyzer crystals and detectors, enabling method-specific optimization across diverse sample matrices.
• Automated high-capacity sampling: 168-position VRC (Variable Radius Carousel) autosampler with barcode recognition, tray flexibility, and direct sample-to-data linkage—minimizing operator intervention and transcription errors.
• Extended instrument uptime: CHI-BLUE coated X-ray tube window resists corrosion from halogen-rich or sulfur-laden samples; active pre-measurement dust removal prevents particulate contamination of optics and detector windows; externally accessible measurement chamber channels allow rapid maintenance without vacuum break or re-stabilization delays.

Sample Compatibility & Compliance

The Axios FAST accommodates solid metals, fused beads, pressed pellets, and thin films—standardized per ASTM E1361, ISO 21043, and EN 15309. Its hardware and firmware comply with IEC 61000-6-2/6-4 for electromagnetic compatibility and IEC 61010-1 for laboratory safety. Software architecture conforms to regulatory expectations for analytical instrumentation used in quality-critical environments: SuperQ software implements full audit trail logging, user role-based access control, electronic signatures, and data integrity safeguards aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements. System validation documentation supports IQ/OQ/PQ protocols for GMP and ISO/IEC 17025-accredited laboratories.

Software & Data Management

SuperQ v10+—the latest iteration of Malvern PANalytical’s industry-proven WDXRF software—provides intuitive workflow-driven operation without sacrificing analytical depth. Method setup includes automated peak deconvolution, matrix correction (e.g., alpha coefficients, fundamental parameters), and empirical calibration management. All processing steps are fully traceable, with version-controlled method files and embedded metadata (operator ID, timestamp, instrument state). Data export supports ASTM E1382-compliant .csv, .txt, and .xlsx formats; optional LIMS integration via OPC UA or TCP/IP ensures seamless transfer to enterprise QA/QC databases. Batch reporting tools generate customizable certificates of analysis (CoA) compliant with ISO/IEC 17025 clause 7.8.

Applications

The Axios FAST serves as a core analytical platform in steelmaking (low-alloy, stainless, tool, and cast iron grade verification), non-ferrous metallurgy (Al, Ti, Cu, Ni alloys), and geochemical laboratories processing iron ore, bauxite, nickel laterite, and slag. It meets the throughput demands of blast furnace feedstock control, continuous caster slab certification, and scrap metal sorting—where results must be delivered within seconds to inform real-time process decisions. Its precision supports specification compliance against ASTM A751, ISO 11576, and JIS G 0320. In contract testing labs, it enables accredited multi-element certification for RoHS, ELV, and REACH screening—particularly where light-element quantification (e.g., Cl in polymers, S in fuels) is required alongside heavy metals.

FAQ

What is the minimum detectable concentration for sodium using the HiPer channel?
Detection limits for Na are typically 30–50 ppm in fused glass beads under standard operating conditions; actual values depend on sample matrix, measurement time, and background suppression.
Can the Axios FAST analyze liquids or powders directly?
Yes—liquids require sealed sample cups with ultrathin polymer films; powders are analyzed as pressed pellets or fused beads; direct analysis of loose powders is not recommended due to heterogeneity and surface topography effects.
Is remote diagnostics supported?
Yes—integrated Ethernet connectivity enables secure remote monitoring, error log retrieval, and guided troubleshooting via Malvern PANalytical’s service portal.
How often does the X-ray tube require replacement?
Under typical industrial usage (8 h/day, 5 days/week), SST-mAX tubes demonstrate >20,000 hours of stable operation; CHI-BLUE coating extends lifetime in corrosive environments.
Does the system support custom calibration development?
Yes—SuperQ includes comprehensive calibration tools for both empirical and fundamental parameter (FP) methods, with full uncertainty propagation and validation reporting per ISO 11097.
