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.

SuperminiThe 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).
