Raying Multi-Position Sample Holder for X-Ray Diffractometers

Overview

The Raying Multi-Position Sample Holder is an engineered mechanical accessory designed specifically for high-throughput X-ray diffraction (XRD) analysis on laboratory-scale diffractometers. It operates on the principle of precise mechanical indexing—leveraging stepper motor-driven rotational or linear translation stages to position up to six pre-mounted samples within the X-ray beam path without manual intervention. This device is not a standalone instrument but a system-integrated component that interfaces directly with the goniometer control architecture and XY sample stage of Rigaku SmartLab series diffractometers. Its design adheres to standard kinematic mounting protocols (ISO 10110-7 compliant interface geometry), enabling repeatable positioning accuracy within ±5 µm in lateral displacement and ±0.005° in angular alignment—critical for maintaining Bragg condition consistency across sequential scans. The holder supports both reflection-mode and transmission-mode configurations, making it suitable for routine phase identification, crystallinity assessment, and thin-film texture analysis in academic, industrial QC, and materials R&D laboratories.

Key Features

• Simultaneous accommodation of six standard 25 mm × 25 mm or 32 mm × 32 mm sample holders (e.g., glass slides, silicon wafers, or aluminum sample cups)
• Motorized indexing synchronized with diffractometer’s scan sequence via TTL-triggered I/O interface or RS-232/USB command protocol
• Integrated limit-switch feedback for real-time position verification and error recovery during unattended operation
• Modular mounting plate compatible with Rigaku SmartLab’s XY-stage dovetail rail system; adaptable to Bruker D2 PHASER and PANalytical Empyrean platforms via custom adapter kits
• Aluminum 6061-T6 construction with hard-anodized surface finish (≥25 µm thickness) for long-term dimensional stability and corrosion resistance in ambient lab environments
• Zero-backlash precision gear train ensuring positional repeatability over >100,000 cycles without recalibration

Sample Compatibility & Compliance

The holder accommodates solid-state specimens including powdered ceramics, metal alloys, pharmaceutical APIs, geological minerals, and thin-film coatings deposited on rigid substrates. It supports sample thicknesses from 0.1 mm to 4 mm and mass loading up to 5 g per position without vibration-induced misalignment. All mechanical components comply with ISO 9001:2015 manufacturing controls, and the electrical interface meets IEC 61000-6-3 EMC emission standards. When operated under validated SOPs, data generated using this accessory satisfies audit requirements for GLP-compliant XRD workflows and aligns with ASTM E975 (Standard Practice for X-ray Diffraction Analysis of Metals) and ISO 17892-12 (Geotechnical investigation and testing — Laboratory testing of soil — Part 12: Determination of crystalline phase content by X-ray diffraction).

Software & Data Management

The sample holder integrates natively with Rigaku’s SmartLab Studio II software through predefined macro scripts that auto-increment sample ID tags and embed position metadata into each .raw file header. For third-party systems, Raying provides open-command-set documentation (ASCII-based SCPI-like syntax) supporting integration with Python-controlled automation frameworks (e.g., PyXRD, GSAS-II batch pipelines) and LabVIEW-based test sequencing. All position logs and trigger timestamps are recorded in CSV format alongside diffraction data, enabling full traceability required under FDA 21 CFR Part 11 for regulated environments. Audit trails include operator ID, start/stop time, sample position index, and any system fault codes—retained for ≥36 months as per internal QA policy.

Applications

• High-volume screening of catalyst libraries in heterogeneous catalysis research
• Batch-to-batch crystallinity verification of active pharmaceutical ingredients (APIs) in GMP manufacturing
• Automated thermal stability profiling via in-situ XRD with programmable heating stages
• Multi-sample stress/strain mapping in metallurgical QA labs using sin²ψ analysis
• Time-resolved phase evolution studies in battery electrode materials during electrochemical cycling

FAQ

Is this sample holder compatible with non-Rigaku diffractometers?
Yes—custom mechanical and electrical adapters are available for Bruker D8 ADVANCE, PANalytical X’Pert PRO, and Thermo Scientific ARL EQUINOX systems upon request.
Does the holder require external power or controller hardware?
It operates via the host diffractometer’s auxiliary power supply (24 V DC) and does not need a separate controller; only firmware-level configuration is required.
Can the holder be used for grazing-incidence XRD (GIXRD)?
Yes—its low-profile design (height ≤ 12 mm above stage surface) permits incidence angles down to 0.5° without beam obstruction.
What is the maximum allowable sample weight per position?
5 grams per slot, with center-of-mass offset limited to ±1.5 mm from nominal axis to maintain dynamic balance during indexing.
Is remote monitoring supported during overnight runs?
Yes—integration with Rigaku’s Remote Monitor service enables real-time status viewing, emergency pause, and email alerts upon job completion or fault detection.
