Free Lime Quantification in Clinker with Simultaneous Wavelength Dispersive X-ray Fluorescence Spectrometer

By Mitsuru Watanabe, Rigaku Corporation


Cement is used for concrete in construction and architectural structures. Clinker, which is an intermediate material for cement, is produced by mixing and calcinating cement raw materials such as limestone, clay and silica in a rotary kiln at a high temperature. The unreacted calcium oxide remaining after calcination of the clinker is called free lime (f.CaO). When calcination in a rotary kiln is insufficient, limestone, the main raw material, does not react sufficiently with silicon dioxide, aluminum oxide, etc., and the amount of free lime increases, resulting in the cement not meeting the expected composition.

Identification of Hazardous Compounds and Illicit Drugs with the Handheld Raman Spectrometers

By Taro Nogami, Rigaku Corporation


Raman spectrometry is becoming a common method for identification of hazardous compounds and illicit drugs. Historically, infrared absorption spectroscopy was the common method, but the mainstream has gradually shifted to Raman spectroscopy. In particular, Raman spectrometry has a couple of advantages over infrared spectrometry for onsite rapid analysis. First, handheld Raman spectrometers can analyze contents through transparent or translucent containers, which infrared absorption spectrometers cannot. Second, Raman spectrometer can analyze wet samples, but infrared absorption spectrometer cannot.

Evaluation of Crystallite Size and Pore Size Distribution of Fuel Cell Materials in a Hydrogen Gas Atmosphere

Rigaku Corporation


A fuel cell is made of a membrane-electrode assembly (combination of anode, polymer electrolyte membrane, and cathode) connected to multiple cells consisting of gaskets and separators. Hydrogen and methanol gases supplied at the anode are decomposed into protons and electrons by catalytic reactions. In this reaction, platinum nanoparticles supported on carbon are used as the catalyst. Note that an increase in the average pore size of platinum catalysts is strongly involved with the degradation of fuel cells.

Quantitative Analysis of Polymorphic Impurities in a Drug Substance by the Calibration Method Using a Benchtop X-ray Diffractometer

Rigaku Corporation


Polymorphic forms and hydrates are different in solubility and absorption, so it is important to control and evaluate them during drug development and manufacturing. Here is an example where we calculated the amount of polymorphic impurities in a drug substance using a high-speed 1D detector, which can obtain intensity data sufficient for qualitative and quantitative analysis in a short period of time, with a benchtop X-ray diffractometer to obtain diffraction data and perform quantitative analysis by the calibration method.

Quantitative Analysis of Soda-lime Glass with Supermini200

Rigaku Corporation


Glass is very common material used in various situations with long historical roots. Soda-lime glass is considered to be the first human made glass, and is still being used in many forms such as light bulbs for lamps, touch panels, LCD monitors, solar panels, insulators, tableware, containers, windows and mirrors. Although the basic component of glass is SiO2, elements such as Na2O and CaO are added to change the characteristics of the glass depending on the intended use.

Cl, Pb and Metals in Refuse Derived Fuel

Applied Rigaku Technologies


Refuse Derived Fuel (RDF) is non-hazardous industrial and packaging waste that cannot be recycled, and is comprised of plastics, paper, textiles, rubber and wood. The material is cleaned using mechanical and biological treatments, crushed, and then sorted to extract the PVC and metal impurities. RDF can safely be used as an alternative fuel source instead of fossil fuels in rotary kilns at lime works and cement plants.

June 17, 2020: Recent devastating fires in the Amazon rain forest and the Australian bush highlight the need to detect forest fires at early stages, before they blaze out of control. Current methods include infrared imaging satellites, remote sensing, watchtowers and aerial patrols, but by the time they sound the alarm, it could be too late. Now researchers have developed self-powered ''paper chips'' that sense early fires and relay a signal.


June 17, 2020: Bose-Einstein condensates are often described as the fifth state of matter: At extremely low temperatures, gas atoms behave like a single particle. The exact properties of these systems are notoriously difficult to study. In the journal "Physical Review Letters", physicists from Martin Luther University Halle-Wittenberg (MLU) and Ludwig Maximilian University Munich have proposed a new theory to describe these quantum systems more effectively and comprehensively.
