Quantification of Trace Crystal Polymorph Components using a High-speed 1-Dimensional Detector

Quantification of Trace Crystal Polymorph Components using a High-speed 1-Dimensional Detector

4 Jan 2016

Materials with the same chemical formula but different crystal structures are called polymorphs. Since an X-ray diffraction profile depends on the crystal structure of the measured materials, XRD is used to evaluate crystal polymorphs. In this application note, a trace component of anatase, a commercially sold reagent, was evaluated with a standard addition method by using a high-speed 1-dimensional detector.

UltimaIV

Rigaku Corporation

The Ultima IV represents the state-of-the-art in multipurpose X-ray diffraction (XRD) systems. Incorporating Rigaku's patented cross beam optics (CBO) technology for permanently mounted, permanently aligned and user-selectable parallel and focusing geometries, the Ultima IV X-ray diffractometer can perform many different measurements fast.With a multipurpose diffractometer, performance is measured by not only how fast you perform an experiment but also how fast you can switch between different types of experiments. Individual experiments are optimized with accessories like the D/teX Ultra high-speed position sensitive detector system, but the speed between experiments is radically improved with the combination of the automated alignment and CBO.The Ultima IV is the only XRD system on the market today that incorporates fully automatic alignment. When coupled with CBO and the in-plane arm, the automatic alignment capability makes the Ultima IV X-ray diffractometer the most flexible system available for multipurpose applications.UltimaIV Features: Full automated alignment under computer control. Optional in-plane diffraction arm for in-plane measurements without reconfiguration. Focusing and parallel beam geometries without reconfiguration. SAXS capabilities. Optional D/teX Ultra high-speed, position-sensitive detector system.

SmartLab

Rigaku Corporation

The SmartLab is the most novel high-resolution diffractometer available today. Perhaps its most novel feature is the SmartLab Guidance software, which provides the user with an intelligent interface that guides you through the intricacies of each experiment. It is like having an expert standing by your side. The system incorporates a high resolution θ/θ closed loop goniometer drive system, cross beam optics (CBO), an in-plane scattering arm, and an optional 9.0 kW rotating anode generator.Coupling a computer controlled alignment system with a fully automated optical system and the Guidance software makes it easy to switch between hardware modes, ensuring that your hardware complexity is never holding back your research.Whether you are working with thin films, nanomaterials, powders, or liquids the SmartLab will give you the functionality to make the measurements you want to make when you want to make them.SmartLab Features: Full automated alignment under computer control. Optional in-plane diffraction arm for in-plane measurements without reconfiguration. Focusing and parallel beam geometries without reconfiguration. SAXS capabilities.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography. Find the best XRD and XRF spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.

Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.Trace Level ImpuritiesTrace level impurities refer to low concentrations of unwanted substances found in chemicals, pharmaceuticals, and other products. Detecting and removing these impurities is crucial for product safety and regulatory compliance.
