Available Methods and Accessories
The Rigaku ZSX Primus IV is a wavelength-dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis of a wide range of materials. It can analyze major and minor elements from boron (B) to uranium (U), depending on measurement conditions and configuration. The instrument is equipped with a tube above configuration, a 4 kW X-ray source, automated sample handling, and wavelength-dispersive detectors for high-resolution elemental analysis.
Available Capabilities
• Qualitative and quantitative elemental analysis
• Semi-quantitative analysis (standardless)
• Major and minor element analysis (ppm levels)
• Point and multi-point analysis
• Elemental mapping
• Analysis of powders, solids, liquids, and thin films
Sample Requirements
• Powders: approximately 5 mg–10 g, depending on
sample preparation and analysis
• Solid samples and films: maximum approximately 50
mm diameter × 30 mm height
• Liquids: minimum approximately 20 mL
• Samples should be representative of the material
being analyzed and suitable for XRF measurement
Summary of Technique
X-ray fluorescence (XRF) spectroscopy determines the elemental composition of a sample by irradiating it with an X-ray beam. The incident X-rays excite atoms in the sample, causing them to emit characteristic X-rays. In wavelength-dispersive XRF (WDXRF), analyzing crystals separate the emitted X-rays according to wavelength, allowing individual elements to be identified and quantified with high spectral resolution. The ZSX Primus IV can perform qualitative, semi-quantitative, and quantitative elemental analysis, including standardless analysis for many sample types.
