Thermo Scientific ARL EQUINOX 100 X-ray Diffractometer

Overview

The Thermo Scientific ARL EQUINOX 100 is a compact, benchtop X-ray diffractometer engineered for high-throughput qualitative and quantitative phase analysis in quality assurance/quality control (QA/QC), academic research, and industrial process laboratories. Unlike conventional θ–2θ scanning diffractometers, the ARL EQUINOX 100 employs a fixed-geometry, real-time detection architecture based on a curved position-sensitive detector (PSD) and a microfocus sealed-tube X-ray source. This design enables simultaneous acquisition of the full diffraction pattern across a continuous 0–110° 2θ angular range—eliminating mechanical scanning, reducing measurement time to seconds, and enhancing long-term stability and reproducibility. Its air-cooled, plug-and-play operation removes dependency on chilled water or dedicated HVAC infrastructure, making it suitable for deployment in constrained lab spaces, mobile analytical units, or production-floor environments where footprint and operational simplicity are critical.

Key Features

• Real-time, non-scanning data acquisition over 0–110° 2θ using a curved PSD—no goniometer movement, no step-scan delays
• Microfocus Cu Kα X-ray source with stable intensity output and minimal beam divergence, optimized for powder, thin-film, and bulk sample geometries
• Benchtop form factor occupying less than one-third the floor space of conventional floor-standing XRD systems
• Integrated air-cooling system; operates from standard AC power (100–240 V), eliminating need for external chillers or water lines
• Modular sample stage support for both reflection (Bragg–Brentano) and transmission geometries, including holders for powders, solids, thin films, and in situ cells
• Pre-aligned optical path and factory-calibrated detector—minimal user alignment required post-installation

Sample Compatibility & Compliance

The ARL EQUINOX 100 accommodates a broad range of sample types without hardware modification: loose powders, pressed pellets, solid metal/ceramic blocks, thin-film coatings on substrates, and capillary-mounted samples for transmission mode. Optional accessories include automated sample changers, heating/cooling stages (up to 1000 °C), and grazing-incidence (GIXRD) and X-ray reflectivity (XRR) collimation kits. The instrument supports compliance-critical workflows through software audit trails, user access levels, and electronic signature capability aligned with FDA 21 CFR Part 11 requirements when configured with Thermo’s optional compliance-ready software package. Data integrity and traceability conform to ISO/IEC 17025 and ASTM E1421 standards for X-ray diffraction measurements.

Software & Data Management

Controlled via Thermo Scientific’s proprietary EQUINOX Software Suite, the system provides intuitive acquisition, real-time pattern visualization, and integrated analysis tools—including phase identification (ICDD PDF-4+ database integration), Rietveld refinement (using TOPAS engine), crystallite size and microstrain evaluation (Williamson–Hall and Warren–Averbach methods), lattice parameter determination, and quantitative phase analysis (QPA) via internal standard or reference intensity ratio (RIR) approaches. Raw data are stored in vendor-neutral binary formats (.raw, .xye) and fully exportable to third-party platforms such as GSAS-II, FullProf, or MATLAB. All processing steps are logged with timestamps, operator ID, and parameter metadata to support GLP/GMP documentation and laboratory audit readiness.

Applications

The ARL EQUINOX 100 delivers robust performance across diverse analytical use cases: rapid phase identification in raw materials and finished products; quantification of polymorphic content in pharmaceuticals; assessment of crystallinity and amorphous fraction in polymers and battery cathode materials; crystallographic texture analysis in metallurgical QA; thin-film thickness and density profiling via XRR; in situ thermal or humidity-driven phase transformation studies; and routine verification of crystal orientation in semiconductor wafers and piezoelectric ceramics. Its speed and reliability make it especially suited for high-volume screening in cement, mining, catalyst, and advanced materials manufacturing settings.

FAQ

Does the ARL EQUINOX 100 require liquid nitrogen or external cooling?

No—it uses an air-cooled microfocus X-ray tube and requires only standard AC power.
Can it perform Rietveld refinement?

Yes—when paired with the optional TOPAS-based analysis module, full-profile Rietveld refinement is supported.
Is GIXRD possible with this instrument?

Yes—using the optional grazing-incidence collimator kit and appropriate sample stage alignment.
What is the typical measurement time for a full-pattern acquisition?

From 1 to 30 seconds depending on sample absorption, desired signal-to-noise ratio, and count time per frame.
Are calibration standards included?

Yes—a certified NIST SRM 660c (LaB₆) reference standard is supplied for angular calibration and peak shape validation.
