Supermini 200 Benchtop WDXRF Spectrometer

This application note from Rigaku Corporation is related to a news article on SelectScience which can be found here. In the application note it is discussed how x-ray fluorescence spectrometers are used to analyze steel to measure bulk metal and powders. In this example the Supermini200 from Rigaku Corporation is used.

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, LCD monitors 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. Addition of different elements in certain quantities can change the physical and chemical properties such as melting point, moisture resistance and thermal expansion. Some trace elements can color glass. X-ray fluorescence (XRF) analysis quickly and easily offers precise elemental analysis results allowing control of glass composition in the production process. This application note describes the analysis of soda-lime glass using the Supermini200.

Both dolomite and limestone are important mineral resources used in various industries such as cement, electronics, iron manufacturing, glass, paper and pulp, agriculture with each industry having a particular interest in contents and components of materials. X-ray fluorescence (XRF) analysis quickly and easily offers precise elemental analysis results allowing control of the components in the product during the manufacturing process. This application note demonstrates the excellent performance of Supermini200 for the analysis of dolomite and limestone.

This application note demonstrates quantitative analysis for Portland and aluminate cements by the fusion method according to ASTM C114-11 using the Rigaku Supermini 200, a Benchtop sequential wavelength dispersive XRF spectrometer.

As part of the control of the steel making process, analyses of slag and raw materials such as quicklime and ferroalloys are also required. X-ray fluorescence spectrometers are the most common analysis tools to analyze steel owing to rapid analysis and the ability to measure both bulk metal and powders. This application note describes low alloy steel analysis using the Supermini200 from Rigaku, which is optimized for process control. The results show that, high precision and accurate analysis of the elements in low alloy steel can rapidly be performed using the Benchtop WDX Supermini200.

Cement is one of the most important materials for construction. Many kinds of hydraulic cements, including Portland cement, with various physical properties are produced by changing the composition of clinker minerals. It is therefore important to control the chemical composition of cement products and interim products. This application note demonstrates quantitative analysis for Portland cement by the pressed powder method according to ASTM C114-11 on Rigaku Supermini200, a benchtop sequential wavelength dispersive X-ray fluorescence spectrometer.

Sulfur is a critical element in the petroleum refinery process and in its final products. Since sulfur in petroleum-based fuels contributes to atmospheric pollution, its concentration, especially in automobile fuels, must be strictly controlled. This application note demonstrates that sulfur in petroleum products can be routinely analyzed in both low and high sulfur concentration ranges with excellent accuracy, sensitivity and repeatability using a Benchtop WDXRF spectrometer with minimal site requirements. In particular, the Rigaku Supermini200 benchtop WDXRF system, which does not require external water for cooling an X-ray tube or special power supply, meets the specifications of ASTM D2622-10, which has become more stringent in the recent versions of ASTM D2622, which has become more stringent in the recent versions of ASTM D2622.

Alloy steels with up to 4 or 8% of alloying elements added are called low alloy steels. Low alloy steels are made by adding various elements intended to improve a specific characteristic of steel such as hardenability. Because the concentrations of elements in molten steel are adjusted during the process of steel making, it is important that the elemental composition can be analyzed rapidly. This application note describes low alloy steel analysis using the Supermini200, which has been optimized for process control.

This application note demonstrates the capabilities of a low-cost, benchtop WDXRF spectrometer for rapid quantitative elemental analysis of cement raw meal. This method provides high-throughput, precision and sensitivity, especially for essential light elements, such as Na, S and K. The Rigaku Supermini200 can be used to routinely analyze cement raw meal samples by the pressed powder method with excellent accuracy and precision.

This application note describes the conventional calibration method of copper ore concentrate analysis and also standardless analysis using the fundamental parameter method. X-ray fluorescence spectrometry is the best method for the analytical requirements of routine analysis to monitor ore grade with high precision, accuracy and rapidity. The Supermini200 from Rigaku provides calibration accuracy with repeatability results that are precise enough to use for daily analysis.
