Phenom XL Sample Holder for Phenom XL G2 Desktop Scanning Electron Microscope

Overview

The Phenom XL Sample Holder is the standard, high-capacity specimen stage engineered exclusively for the Phenom XL G2 Desktop Scanning Electron Microscope — a benchtop SEM system designed for industrial and academic laboratories requiring rapid, high-resolution imaging of large, uncoated, or irregularly shaped samples. Unlike conventional SEM stages limited to 30–50 mm diameter specimens, the XL Sample Holder leverages a patented vacuum-compatible mechanical loading mechanism that accommodates specimens up to 100 mm × 100 mm in planar dimension and 65 mm in height. This architecture eliminates the need for sample sectioning or repeated chamber venting, enabling true “large-area” analysis without compromising vacuum integrity or operational throughput. The holder integrates seamlessly with the XL G2’s integrated low-vacuum mode and CeB₆ electron source, supporting high signal-to-noise imaging of conductive, semi-conductive, and non-conductive materials — including as-received metallographic mounts, geological cores, PCB assemblies, and composite laminates — without mandatory sputter coating.

Key Features

• Maximum specimen footprint: 100 mm × 100 mm × 65 mm (H), enabling single-session analysis of oversized or multi-sample arrays
• Patented fast-load vacuum interface reduces pump-down time to < 45 seconds — significantly exceeding industry benchmarks for desktop SEM throughput
• Modular insert compatibility: supports three standardized metallographic resin-mount inserts (e.g., 25 mm, 30 mm, and 35 mm diameters), allowing direct placement of polished cross-sections per ASTM E3, ISO 14487, and ASTM E1558
• Integrated mechanical stage alignment with sub-micron repeatability; compatible with automated multi-point acquisition and stitching workflows
• Robust aluminum alloy construction with electroless nickel plating ensures long-term dimensional stability, ESD safety, and resistance to chemical exposure during routine lab handling
• Designed for full interoperability with Phenom’s proprietary backscattered electron (BSE) and secondary electron (SE) detectors, as well as optional energy-dispersive X-ray spectroscopy (EDS) modules

Sample Compatibility & Compliance

The Phenom XL Sample Holder extends analytical flexibility across diverse material classes while maintaining regulatory readiness for quality-critical environments. It accommodates uncoated metallic, ceramic, polymer, and biological specimens — including epoxy-embedded metallurgical mounts, fractured fracture surfaces, solder joints, and mineral thin sections. Its geometry complies with ISO/IEC 17025 requirements for instrument calibration traceability when used with certified reference standards (e.g., NIST SRM 2090a). For regulated manufacturing settings, the holder supports audit-ready documentation workflows under GLP and GMP frameworks, particularly when paired with Phenom’s software-enabled user access control, electronic signature, and 21 CFR Part 11-compliant audit trail features.

Software & Data Management

Operation is fully integrated with Phenom’s Thermo Scientific™ Phenom Desktop Software Suite (v5.x+), which provides intuitive stage navigation, real-time drift correction, and automated montage generation for areas exceeding single-field-of-view dimensions. All stage position metadata — including X/Y/Z coordinates, tilt angle, and magnification — are embedded directly into TIFF and HDF5 output files. Data export supports FAIR principles (Findable, Accessible, Interoperable, Reusable) via standardized metadata schemas compliant with MIAME and MIAPE guidelines. Raw image datasets can be exported for downstream processing in third-party platforms such as ImageJ/Fiji, MATLAB, or Thermo Scientific Avizo.

Applications

• Metallography & failure analysis: Rapid assessment of grain structure, inclusion distribution, and interfacial integrity in castings, welds, and additive-manufactured components
• Electronics inspection: Full-board scanning of PCBs, flex circuits, and semiconductor packaging without disassembly or cropping
• Geosciences: High-throughput imaging of drill core slabs, thin-section mosaics, and unprepared sediment aggregates
• Materials R&D: In-situ monitoring of corrosion progression, coating delamination, and thermal aging effects across cm-scale regions
• Forensics & cultural heritage: Non-destructive surface characterization of toolmarks, paint layers, and archaeological artifacts at micron-scale resolution

FAQ

Is the Phenom XL Sample Holder compatible with earlier Phenom models (e.g., Phenom ProX or Pure)?

No — it is mechanically and electronically optimized exclusively for the Phenom XL G2 platform and cannot be retrofitted to prior-generation instruments.
Can the holder accommodate tilted or angled specimens?

Yes — the stage accepts custom tilt adapters (sold separately) supporting ±45° rotation around the horizontal axis, enabling cross-sectional BSE contrast optimization.
Does the holder require special maintenance or cleaning procedures?

Routine cleaning with lint-free wipes and isopropyl alcohol is sufficient; no lubrication or recalibration is required between uses.
Is EDS mapping supported across the full 100 × 100 mm area?

Yes — via stage-synchronized raster scanning and spectral accumulation, though dwell time per pixel must be adjusted based on beam current and detector solid angle constraints.
Are replacement inserts for metallographic mounts available as spare parts?

Yes — Phenom offers certified inserts for 25 mm, 30 mm, and 35 mm diameter resin mounts (P/N: XL-MET-25, XL-MET-30, XL-MET-35) with documented flatness tolerances ≤ 1 µm.
