Supermini200 Applications



Advanced SQX Analysis by Scatter FP Method - 1036


This application note introduces some applications by the SQX Scatter FP method.

Background
Semi-quantitative analysis by the Fundamental Parameter (FP) method is a unique and powerful method for elemental screening of materials. In the FP calculation, the program requires principally the information of all elements included in a specimen for analysis. This requirement is not convenient when the specimen contains large amount of ultra-light elements from hydrogen to oxygen, which are difficult to determine accurately or non-measureable elements on X-ray spectrometry.

In 2005, Rigaku developed a new method to estimate an average atomic number for non-measured elements from hydrogen to oxygen in a specimen using the intensities of scattered X-rays and applied the estimation to the semi-quantitative FP calculation (SQX) as a balance component.

The successfully advanced SQX method using scattering intensities, the SQX Scatter FP method becomes available for oxide powders on the newly developed benchtop XRF spectrometer, Supermini200.




Analysis of Low Concentration Sulfur in Petroleum-based Fuels by Benchtop WDXRF According to ASTM D2622-10


This application note demonstrates quantitative analysis of low concentration sulfur in diesel fuel, gasoline and kerosene according to ASTM D2622-10 on Rigaku Supermini, a benchtop wavelength-dispersive X-ray fluorescence (WDXRF) spectrometer.

Background
Sulfur in petroleum-based fuels contributes to atmospheric pollution. Sulfur content in fuels, especially in automobile fuels, is strictly controlled and regulations of sulfur content in fuel oil, such as diesel fuel and gasoline, have been tightened. Therefore, control of sulfur content is very important in refineries. X-ray fluorescence (XRF) spectrometry has been used for quantitative analysis of sulfur in petroleum-based fuels, owing to simple sample preparation. In XRF analysis of fuel oil, the sample is simply poured into a plastic cup equipped with a transparent film without any complicated treatment, such as chemical decomposition or serial dilution. In addition, concentration of total sulfur is obtained in XRF analysis.




ASTM 2622 compliance for petroleum products on the Rigaku Supermini200



Background

ASTM 2622 - 08 lays out the expected performance from a WDXRF for the analysis of sulfur in petroleum products from 3 mg/kg to 4.6% sulfur. The analysis of sulfur is necessary to help refineries to meet legislated limits set by governmental agencies such as the EPA and State Air Resource Boards. Sulfur is linked to the formation of nitrous oxides in the atmosphere, which are the main cause of smog and also participate in the formation of ozone. Both of these conditions are the source of adverse health effects on the public at large and considered public health hazards.

The use of an internationally recognized standard such as ASTM or ISO allows the industry as a whole to carry out these measurements in exactly the same way making sure that products sulfur content is measured uniformly by all parties, the producer, the referee, and the consumer groups who monitor these parameters.

The Rigaku Supermini200 is ideal for characterizing the sulfur levels in all of the petroleum feedstocks, intermediates and final products.




Cement Analysis by the Fusion Method on Benchtop WDXRF Supermini200 According to ASTM C114-11


This application note demonstrates quantitative analysis for Portland and aluminate cements by the fusion method according to ASTM C114-11 on Rigaku Supermini200, a benchtop sequential wavelength dispersive XRF spectrometer.

Background
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; therefore, it is important to control the chemical composition of cement products and interim products.

Since the fusion method can eliminate sample heterogeneity, such as grain size and mineralogical effects, it is possible to obtain high accuracy for cement samples and also to establish calibrations using a variety of materials. Therefore, X-ray fluorescence (XRF) spectrometry by the fusion method has been the method of choice in cement production processes.

ASTM C114-11 covers chemical analysis of hydraulic cements. In this standard, procedures of wet chemical analysis are mainly described and XRF spectrometry is mentioned as example of “Rapid Test Methods”. In practice, XRF spectrometry has been used for chemical composition analysis of cement owing to its simple sample preparation and high precision.

Cement Raw Meal Analysis by the Pressed Powder Method on Benchtop WDXRF Supermini200


This application note demonstrates the capabilities of a low-cost, benchtop WDXRF spectrometer for rapid quantitative elemental analysis of cement raw meal.

Background
Thanks to simple sample preparation and routine operation, short measurement times and high precision, X-ray fluorescence (XRF) spectrometry has become the technique of choice for elemental analysis at all points in cement production: from alternative fuels, raw materials and raw meal to clinker and final certification. Wavelength-dispersive (WD) XRF is the most commonly utilized analytical technique in the cement industry because it offers the highest throughput, precision and sensitivity, especially for essential light elements, such as Na, S and K.

Traditionally, WDXRF spectrometers used in cement plants have been large, floor-standing models with substantial installation requirements and ownership expenses. As the industry strives for greater efficiency, operators have increasingly sought equipment that is less expensive to acquire and less costly to maintain.




Copper Concentrate Analysis by Pressed Powder Method


This application note will show the conventional calibration method of copper ore concentrate analysis and also standardless analysis using the fundamental parameter method.

Background
Copper is one of the essential base metals in modern infrastructure. It is used for construction, electronics, machinery, automobile and marine vessel etc. in the form of electric cable and copper alloys.

Copper ore mined as mainly sulfide ore is usually shipped as concentrate of 20 – 40% in copper content after processing at the plant near mine site.
Copper concentrate contains a variety of impurities that are either valuable elements as byproducts, or harmful to quality in copper metal products and hazardous to the environment and human health. In modern copper deposits, ore grade of copper is decreasing while impurities in ore tend to increase. Therefore, the demand for rapid and accurate determination of various metals of major and trace amounts in copper ore and concentrate is increasing.

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.




Drug development



Background
New drug discoveries not only help secure the financial health of pharmaceutical companies, they are paramount to the management of disease and the furtherance of human health and wellness. In the synthesis of new compounds for drug efficacy studies, researchers may be impacted by experimental, budgetary or other constraints as to the quantity of suitably pure material that can be produced in the laboratory for subsequent evaluation. These sample size limitations complicate chemical characterization of the synthetic products since very little material can be sacrificed for analysis.

Rigaku's patented Microcarry and Ultracarry filters offer a uniquely fast, convenient and cost-effective means of conducting reliable elemental analyses of minute quantities of these drug candidates. The high detection sensitivities achievable with this sample preparation method often permit analyses to be conducted on lower cost benchtop WDXRF models with reduced utility and maintenance requirements such as Rigaku's high performance 200 Watt Supermini200 WDXRF spectrometer.

The WDXRF calibration curve shown in Figure 1 was constructed by pipetting microgram quantities of 2-bromo-5-aminothiazole monohydrobromide (Sigma-Aldrich, 61.48 mass% Br theoretical) from a 1.00 mg/mL aqueous stock solution onto the center analysis region of Microcarry filters. Measurement of bromine x-ray emission intensity from duplicate preparations of these filters using the Supermini200 gave a correlation coefficient of 0.998 and accuracy (RMS deviation) of 0.8 micrograms when calibrating in a Br loading range of 0 - 31 micrograms.
