For manufacturers who market a wide range of products, including household products, pharmaceuticals and/or nutraceutical products, it is important to communicate the characteristics of their products to consumers. This often requires a good evaluation technique that can show the product characteristics intuitively. X-ray imaging techniques, which can visualize the internal...

Molecular structure determination is very useful for the development of medicines, aroma chemicals and agrochemicals. Single crystal X-ray diffraction (SC-XRD) analysis is the most powerful technique for molecular structure determination. However, SC-XRD analysis requires good quality crystals. In fact, the biggest hurdle for SC-XRD analysis is crystallization. Crystallization trials require...
It is necessary to obtain high-quality data for highly accurate analysis. The characteristics of high-quality data may be high intensity, high resolution, high P/B (peak-to-background ratio), and high S/N (signal-to-noise ratio). Deciding which features are important depends on the purpose of analysis. Therefore, we need to consider measurement conditions after...
Halogen elements correspond to Group 17 in the periodic table and include fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Materials and products containing halogens are widely used in our daily life. For example, fluorine is contained in Teflon® resin and toothpaste, chlorine is contained in salt and vinyl...
Diffraction-based characterization of epitaxial thin films, such as the measurement of the composition, strain, and lattice constants, requires complicated alignment processes of the X-ray optics. Rigaku’s multipurpose X-ray diffractometer, “SmartLab,” features an automatic alignment function, which greatly simplifies the process. However, it still requires a timeconsuming re-alignment process when, for...
XY mapping measurements to obtain physical values for your analysis purpose is one of the best ways to analyze the state distribution of a substance, the strength distribution of a material or a device, etc. The significant progress in X-ray sources, optical devices and detectors has enabled the irradiated area...
X-ray fluorescence (XRF) spectrometry allows both simple sample preparation and high precision analysis. The method is highly popular among various fields, including quality control and research & development. Recent advanced data processing techniques and higher instrument sensitivities have improved analytical accuracies in “standardless FP analysis” using Fundamental Parameter (FP) method...
