Quantitative Analysis of Low Alloy Steel Using the Supermini200

Rigaku Corporation
8 Nov 2012

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.

Supermini 200 Benchtop WDXRF Spectrometer

Rigaku Corporation

The new Supermini200 has improved software capabilities as well as a better footprint. As the world's only high-power benchtop sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis of oxygen (O) through uranium (U) of almost any material, the Rigaku Supermini200 uniquely delivers low cost-of-ownership (COA) with high resolution and lower limits-of-detection (LLD). Not only is the Rigaku Supermini200 an affordable choice for your XRF elemental analysis needs, the running costs are also low. P10 gas for the flow proportional detector is the only consumable. The Supermini200 does not require a source of cooling water, plumbing, or an external chiller, thereby decreasing system maintenance and lowering the overall lifetime cost of ownership of the system and yearly budgets for consumables and maintenance.Supermini is the only high powered (200 W) X-ray tube benchtop WDXRF system, providing excellent excitation resulting in lower detection limits and shorter measurement times. A unique and proprietary optical system is also employed to enhance sensitivity beyond the gains of the tube power.Supermini 200 Benchtop WDXRF Spectrometer Features: Analyze oxygen through uranium (O → U) Analyze: solids, liquids, powders, alloys and thin films Atmosphere: air, helium or vacuum X-ray tube: 50 kV, 200 W Pd-anode Primary beam filter: Zr is standard; Al optional Detectors: F-PC and scintillation Crystals: 3-position changer Autosampler: 12-position standard Vacuum: rotary pump standard Power: 100 – 120V (50/60 Hz) 15A or 200 – 240V (50/60 Hz) 10A

Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

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.
