Shimadzu EDX-720 Used Energy Dispersive X-ray Fluorescence Spectrometer

Overview

The Shimadzu EDX-720 is a benchtop energy dispersive X-ray fluorescence (EDXRF) spectrometer engineered for precise, non-destructive elemental analysis of solids, powders, liquids, thin films, and irregularly shaped samples—including wafers and magnetic disks. Operating on the principle of X-ray excitation and energy-resolved detection, the instrument irradiates a sample with primary X-rays, inducing characteristic secondary (fluorescent) X-rays whose energies are uniquely associated with atomic number. The Si(Li) detector—coupled with high-stability pulse processing electronics—enables accurate identification and quantification across the elemental range from sodium (Na, Z=11) to uranium (U, Z=92). Designed for regulatory compliance workflows, the EDX-720 delivers trace-level sensitivity essential for environmental screening under RoHS, WEEE, ELV, and global toy safety directives (ASTM F963, EN 71), as well as corporate green procurement standards such as Sony SS-00259 (STM-0083).

Key Features

• Enhanced sensitivity: Optimized X-ray optics and a 5-position automated filter changer suppress spectral background and improve peak-to-background ratios—doubling detection efficiency for critical elements including Pb, Cd, Cr, Br, and Hg.
• High-count-rate electronics: Upgraded pulse processing circuitry supports elevated count rates without significant dead-time loss, enabling robust statistical precision even at short acquisition times.
• Intelligent acquisition control: Real-time intensity-based algorithm calculates required measurement duration to achieve user-specified precision thresholds—minimizing analysis time without compromising data reliability.
• Automated method selection: Software identifies sample type (e.g., polymer, metal, ceramic, liquid) via spectral pattern recognition and selects the most appropriate calibration model—standard curve, fundamental parameters (FP), matrix-corrected FP, thin-film FP, or background-subtracted FP—reducing operator dependency.
• Robust mechanical design: Precision XYZ stage accommodates samples up to Ø300 mm × 150 mm height; vacuum-compatible chamber optional for light-element analysis (Na–F); helium purge capability available for enhanced low-Z sensitivity.

Sample Compatibility & Compliance

The EDX-720 accepts heterogeneous, unprepared specimens—no digestion, coating, or pelletization required—making it ideal for rapid screening in QC labs, recycling facilities, and R&D environments. Its non-invasive nature preserves sample integrity for downstream testing. The system meets analytical requirements defined in IEC 62321-5:2013 (RoHS screening), ISO 17025-accredited validation protocols, and supports audit-ready documentation aligned with GLP and GMP principles. While not certified for FDA 21 CFR Part 11 out-of-the-box, the software architecture permits configuration for electronic signature, audit trail, and user access control—facilitating integration into regulated quality systems upon implementation of site-specific validation procedures.

Software & Data Management

Shimadzu’s proprietary analysis software provides integrated qualitative identification (peak deconvolution, library matching), quantitative analysis (calibration curve, FP, and multi-layer models), and reporting tools compliant with ISO/IEC 17025 documentation standards. All measurement parameters, spectra, and calculation logs are timestamped and stored in a structured database. Raw spectral files (.spe, .qgd) and processed reports (.pdf, .xlsx) are exportable for third-party review or LIMS integration. Version-controlled software updates ensure compatibility with current operating systems and security patches. Post-purchase technical support includes remote diagnostics, firmware revision guidance, and application-specific method development assistance.

Applications

• Routine RoHS/ELV compliance screening of PCBs, connectors, cables, and plastic housings
• Quantitative verification of alloy composition (e.g., stainless steel grade confirmation, solder Sn/Pb ratio)
• Contamination monitoring in semiconductor wafer reclaim processes
• Heavy metal screening in consumer goods (toys, jewelry, cosmetics packaging)
• Geological and environmental sample profiling (soil, sediment, fly ash)
• Quality assurance of catalysts, pigments, and battery materials

FAQ

Is this unit factory-refurbished or dealer-certified?
This EDX-720 is a pre-owned instrument sourced from a Shimadzu-authorized distributor in Japan. It underwent full functional verification, detector performance validation (including resolution and peak shape assessment), and optical alignment calibration prior to resale. A comprehensive inspection report—including detector LN2 fill history, high-voltage stability test results, and filter mechanism cycle count—is provided with shipment.

What documentation accompanies the instrument?
Included are the original English-language operation manual, software license certificate (perpetual use), calibration verification record, maintenance log summary, and CE Declaration of Conformity. No original Japanese-language documents are supplied unless specifically requested.

Can the system be upgraded to vacuum or helium mode?
Yes—the base configuration supports field-installation of vacuum pumping or He gas purge accessories. Retrofit kits and installation services are available through authorized Shimadzu service partners.

Is remote support available post-installation?
Yes. Basic troubleshooting and software configuration support is included during the 6-month warranty period. Extended service contracts covering preventive maintenance, detector reconditioning, and on-site engineering visits can be arranged separately.
