FocusSens MiX5 Series Handheld XRF Alloy Analyzer

Overview

The FocusSens MiX5 Series Handheld XRF Alloy Analyzer is an industrial-grade energy-dispersive X-ray fluorescence (EDXRF) spectrometer engineered for rapid, non-destructive elemental analysis of metallic materials in field and production environments. Leveraging a high-power 50 kV, 4 W rhodium-target X-ray tube and a large-area silicon drift detector (SDD), the MiX5 delivers laboratory-comparable precision with sub-second acquisition times. Its analytical principle relies on characteristic X-ray emission induced by primary X-ray excitation, enabling quantitative determination of elemental composition from magnesium (Mg) to bismuth (Bi) — depending on configuration — with detection limits in the low parts-per-million (ppm) range for key alloying and residual elements. Designed for mission-critical material identification and verification, the MiX5 meets the operational demands of positive material identification (PMI), QA/QC compliance, scrap sorting, and regulatory traceability across process industries.

Key Features

• High-performance EDXRF architecture: 50 kV Rh-target X-ray tube coupled with a high-resolution SDD for optimal light-element (Mg, Al, Si, P, S) sensitivity and heavy-element line separation.
• Real-time alloy grade identification: Full ASTM/ISO-compliant grade matching against preloaded libraries containing >1,600 alloys, including AISI, DIN, JIS, and GB standards.
• User-customizable grade databases: Operators may edit existing entries, add proprietary grades (e.g., OEM-specific weld wire compositions), or build dedicated libraries for niche applications.
• Ruggedized field design: IP54-rated enclosure (NEMA 3 equivalent) with integrated heatsink for stable operation up to 50°C ambient; optional Kapton® window (MiX5 500) or replaceable Be/Al composite windows (MiX5 600/900) for enhanced probe protection.
• Ergonomic handheld form factor: Weighing only 1.5 kg with balanced center-of-gravity design; 4.3-inch sunlight-readable capacitive touchscreen supporting gloved operation.
• Instant startup: Ready for measurement within <5 seconds of power-on; typical analysis time: 1–2 s for grade ID, 5–10 s for full quantitative reporting.

Sample Compatibility & Compliance

The MiX5 accommodates a broad range of metallic samples — solid castings, forgings, welds, pipes, plates, fasteners, and scrap fragments — without surface preparation beyond basic cleaning. Its geometry-optimized collimation enables reliable analysis of curved surfaces, narrow weld beads, and recessed features. The instrument complies with IEC 62471 (photobiological safety), EN 61000-6-3 (EMC), and local radiation safety regulations governing handheld XRF devices. While not certified under FDA 21 CFR Part 11, its audit-ready data logging supports GLP/GMP-aligned workflows when deployed with documented SOPs and user access controls. All firmware and calibration files are traceable to NIST-traceable reference materials via FP (Fundamental Parameters) + empirical coefficient hybrid algorithms.

Software & Data Management

Data integrity and traceability are ensured through embedded storage of up to 100,000 test records, each containing full spectral data, sample image (with optional integrated camera), GPS coordinates, operator ID, timestamp, and environmental metadata. Reports export natively to CSV and PDF formats — both preserving digital signatures and checksums for long-term archival. The X-MET Report Generator (browser-based, no installation required) enables creation of client-branded reports featuring company logos, custom result fields (e.g., “Pass/Fail vs. Spec”), multi-spectrum overlays, and full spectral visualization. Wireless transfer via Wi-Fi or Bluetooth 5.0 supports integration into enterprise LIMS or SAP QM modules; USB-C direct connection allows secure offline data extraction to encrypted USB drives.

Applications

• Positive Material Identification (PMI) in petrochemical, power generation, and pressure vessel fabrication per ASME B31.3 and API RP 578 requirements.
• In-process QA/QC during metal machining, welding, and heat treatment — verifying feedstock conformity prior to costly downstream processing.
• Scrap metal recycling: Rapid segregation of stainless steels, nickel alloys, titanium, and aluminum grades to maximize recovery value and avoid cross-contamination.
• Aerospace MRO: Verification of turbine blade superalloys, landing gear steels, and airframe fasteners against AMS and SAE specifications.
• Archaeometallurgy and cultural heritage studies: Non-invasive compositional profiling of historical artifacts and excavated metal objects.

FAQ

What elements can the MiX5 analyze?

The MiX5 500 detects elements from Ti to Bi; the MiX5 600 adds Mg, Al, Si, P, S, and Ru; the MiX5 900 extends coverage to include As and Ir — all configurations maintain consistent detection limits and precision across their respective ranges.

Is the instrument suitable for regulatory audits?

Yes — when operated under defined procedures, its tamper-evident data logs, user authentication, and calibrated FP+empirical quantification model support ISO/IEC 17025-aligned validation and third-party audit readiness.

How is calibration maintained in the field?

Factory calibrations are traceable to CRM standards; users perform daily verification checks using supplied check standards; periodic recalibration is recommended every 12 months or after 10,000 measurements.

Can the MiX5 be used in hazardous areas?

It is not ATEX or IECEx certified; however, its IP54 rating and absence of moving parts make it suitable for Zone 2/Class I Division 2 environments when deployed with appropriate risk assessment and site-specific permits.

Does the device require annual service contracts?

No mandatory contract is required; however, extended warranty and preventive maintenance packages are available to ensure sustained performance, detector health monitoring, and firmware updates aligned with evolving regulatory expectations.
