HY DX-2700BH Multi-Functional Powder X-ray Diffractometer

Overview

The HY DX-2700BH Multi-Functional Powder X-ray Diffractometer is a θ–θ goniometer-based analytical instrument engineered for high-precision crystallographic characterization of solid-state materials. It operates on Bragg’s law (nλ = 2d sinθ) using monochromatic Cu Kα radiation (λ = 1.5418 Å), enabling quantitative and qualitative phase analysis, lattice parameter refinement, crystallite size estimation via Scherrer analysis, microstrain evaluation, and thin-film structural characterization. Designed for both routine laboratory use and advanced research applications, the system integrates a sealed metal-ceramic X-ray tube with stable high-voltage control, ensuring reproducible intensity output over extended acquisition periods. Its modular θ–θ geometry simplifies sample mounting—particularly for powders, bulk solids, thin films, and micro-region specimens—and facilitates rapid integration of optional accessories without mechanical realignment.

Key Features

• θ–θ optical configuration for enhanced beam collimation, reduced parasitic scattering, and improved angular accuracy across 5°–160° 2θ range
• High-stability metal-ceramic X-ray tube with programmable kV/mA control, supporting long-term thermal equilibrium during sequential or continuous scans
• Dual detection options: sealed proportional counter (standard) and optional silicon drift detector (SDD) offering ≥3× faster data collection, superior energy resolution (<130 eV at Mn Kα), and simultaneous multi-angle acquisition
• Motorized sample stage with precise angular positioning (≤0.0005° step resolution) and automatic alignment recognition for interchangeable accessories
• Plug-and-play modular design: all functional modules—including high-temperature stage, low-temperature cryostat, stress/texture attachment, and micro-beam collimator—are auto-detected by firmware; no manual optical recalibration required
• Robust mechanical construction with precision-ground goniometer bearings and temperature-compensated encoder feedback for long-term angular repeatability (±0.002° 2θ over 12 months)

Sample Compatibility & Compliance

The DX-2700BH accommodates diverse sample forms: loose powders (≥10 mg), pressed pellets, polished bulk metals, freestanding thin films (1 nm–5 µm), and micro-samples (down to 100 µm spot size with optional microfocus optics). It complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and meets radiation safety requirements per GBZ 117–2020 (China) and equivalent ISO 20816-1 vibration tolerance standards. While not certified to FDA 21 CFR Part 11 out-of-the-box, its audit-trail-capable software architecture supports GLP/GMP-aligned validation protocols when deployed in regulated environments (e.g., pharmaceutical polymorph screening per USP or cement phase quantification per ASTM C1365).

Software & Data Management

The bundled HY-Diffraction Suite provides comprehensive data reduction and modeling tools compliant with ICDD PDF-4+ and ICSD database formats. Core capabilities include automated peak search with adaptive background subtraction, full-pattern Rietveld refinement (using GSAS-II or TOPAS-compatible output), crystallite size and microstrain deconvolution (Williamson–Hall and Warren–Averbach methods), texture coefficient calculation (pole figure reconstruction), and residual stress mapping (sin²ψ method). All processing workflows support batch execution, metadata tagging (sample ID, operator, date/time, instrument parameters), and export to CIF, XYE, CSV, or HDF5 formats. Audit trails record user actions, parameter changes, and version-controlled processing scripts—enabling traceability per ISO/IEC 17025:2017 clause 7.7.

Applications

• Phase identification and quantification in geological samples (clays, zeolites, asbestos minerals) per ASTM D7657
• Polymorph screening and stability assessment of active pharmaceutical ingredients (APIs)
• Crystallinity index determination in semi-crystalline polymers and biopolymers
• Thin-film analysis: layer thickness, interfacial roughness, and epitaxial strain in oxide heterostructures
• Residual stress profiling in aerospace alloys and additive-manufactured components
• In-situ/operando studies using environmental stages (ambient to 1200°C, or −180°C to +500°C with cryo/gas modules)
• Nanomaterial characterization: size distribution, lattice distortion, and defect density in quantum dots or MOFs

FAQ

What X-ray source options are available for the DX-2700BH?
The standard configuration uses a sealed Cu-target metal-ceramic X-ray tube (max 45 kV / 40 mA); optional Mo, Co, or Cr anodes are available for specialized wavelength requirements.
Does the system support Rietveld refinement natively?
Yes—the HY-Diffraction Suite includes integrated Rietveld engine with parameter constraints, profile fitting, and structure model import from CIF files.
Can the diffractometer be validated for GMP compliance?
While factory calibration certificates are provided, formal GMP validation requires site-specific IQ/OQ/PQ protocols developed jointly with end-user QA teams.
Is remote operation supported?
The software supports secure LAN/WAN access via VNC or RDP; however, real-time detector control requires local network latency <10 ms for optimal synchronization.
What maintenance intervals are recommended?
X-ray tube lifetime is rated at ≥5,000 hours under nominal conditions; proportional counter gas replenishment is required every 24 months; annual goniometer calibration verification is advised.
