Multi-TF Thin-Film Multi-Position Sample Holder for Rigaku SmartLab X-ray Diffractometers

Overview

The Multi-TF Thin-Film Multi-Position Sample Holder is an engineered mechanical accessory designed specifically for high-precision X-ray diffraction (XRD) platforms—primarily the Rigaku SmartLab series—enabling automated, sequential analysis of multiple thin-film specimens without manual intervention. Based on the fundamental geometry of Bragg’s law and optimized for θ–2θ scanning configurations, the holder integrates mechanically with the instrument’s motorized XY sample stage to deliver repeatable angular alignment and positional accuracy critical for techniques including conventional XRD, grazing-incidence XRD (GIXRD), and X-ray reflectivity (XRR). Its patent-protected design (CN202020383306.0) ensures stable sample registration across repeated thermal and mechanical cycles, minimizing drift-induced intensity variation and enabling unattended overnight acquisition protocols in regulated laboratory environments.

Key Features

• Motorized multi-position indexing mechanism supporting 3 to 11 standardized thin-film substrates (e.g., Si wafers, glass slides, or coated quartz plates) with sub-50 µm positional repeatability.
• Direct mechanical coupling to Rigaku SmartLab’s native XY stage controller via OEM-compatible mounting interface; no firmware modification required.
• Modular carrier plate system allows rapid reconfiguration for varying substrate dimensions (10 × 10 mm to 50 × 50 mm) and thicknesses (0.1–2 mm).
• Low-background aluminum alloy construction with black anodized surface finish to minimize parasitic scattering during low-intensity measurements.
• Integrated reference fiducial markers for automated optical alignment verification using optional camera-based setup tools.
• Designed for ambient and controlled-humidity operation; not rated for vacuum or inert-gas glovebox integration without third-party enclosure adaptation.

Sample Compatibility & Compliance

The Multi-TF holder accommodates rigid planar thin-film samples prepared by sputtering, PLD, spin-coating, or CVD—common in semiconductor, ferroelectric, and optical coating R&D. It supports standard specimen geometries compliant with ISO 17873:2014 (X-ray diffraction — Terminology and conventions) and aligns with ASTM E975-20 (Standard Practice for X-ray Diffraction Crystallographic Analysis) requirements for sample positioning reproducibility. While the holder itself is not a measurement device subject to FDA or CE regulatory classification, its use in GLP/GMP-aligned laboratories adheres to traceability principles when paired with audit-ready SmartLab software logging. No electrical safety certification (e.g., UL/IEC 61010) applies, as it contains no powered components.

Software & Data Management

Operation is fully integrated into Rigaku’s SmartLab Studio II software suite via native stage command mapping. Users define sample sequence order, dwell time per position, and scan parameters (2θ range, step size, counting time) within a single acquisition script. All positional metadata—including absolute XY coordinates, sample ID tags, and timestamped run logs—are embedded in the .raw and .csv output files. The system supports batch processing workflows compatible with third-party analysis packages such as GSAS-II, DIFFRAC.SUITE TOPAS, and PANalytical HighScore Plus. Audit trail functionality meets baseline requirements for 21 CFR Part 11-compliant environments when deployed with SmartLab’s optional electronic signature and user access control modules.

Applications

• High-throughput screening of combinatorial thin-film libraries for phase identification and crystallite size analysis.
• Time-resolved structural evolution studies under thermal ramping or environmental stimuli (when used with in-situ stages).
• Quantitative layer-by-layer characterization in multilayer heterostructures via XRR modeling.
• Grazing-incidence diffraction mapping of epitaxial strain gradients across wafer-scale samples.
• Quality control in pilot-line deposition processes where inter-batch consistency must be verified across ≥5 representative sites.

FAQ

Is the Multi-TF holder compatible with non-Rigaku diffractometers?
Yes—mechanical adaptation kits are available for Bruker D8 ADVANCE, PANalytical Empyrean, and Thermo Scientific ARL EQUINOX systems; contact Raying technical support for interface drawings and torque specifications.
Does it require external power or communication cables?
No—the holder is purely passive and driven solely by the host diffractometer’s XY stage motors; no additional wiring or driver software installation is needed.
What is the maximum allowable sample weight per position?
Each slot supports up to 15 g total mass, assuming uniform distribution and flat substrate geometry; heavier or warped samples may affect positional fidelity and require custom clamping solutions.
Can the holder be sterilized or cleaned with solvents?
Wipe-down with isopropanol or acetone is permitted; ultrasonic cleaning or autoclaving is not recommended due to adhesive bonding and precision-machined tolerances.
Is firmware or software update support included during warranty?
Yes—Raying provides quarterly compatibility patches for SmartLab Studio II updates and maintains backward compatibility for all versions released within the prior 36 months.
