ZSX Primus III NEXT High-Throughput/Affordable WDXRF Spectrometer

Description

Designed for cost-effective industrial elemental analysis, the Rigaku ZSX Primus III NEXT is a wavelength-dispersive X-ray fluorescence (WDXRF) spectrometer that balances high throughput with an accessible price point. It is capable of rapid quantification of elements from beryllium (Be) to curium (Cm), covering both major constituents and trace components. The system incorporates a tube-above optical configuration, which positions the X-ray tube above the sample chamber. This design helps prevent analytical drift caused by particulate contamination of the optics, a feature particularly beneficial for analyzing pressed powder samples common in sectors like mining, cement, ceramics, and petrochemicals. The spectrometer uses a 3 kW end-window rhodium target X-ray tube. Standard detectors include a scintillation counter (SC) and a gas flow proportional counter (F-PC), with an optional sealed proportional counter (S-PC LE) for light elements that eliminates the need for P-10 gas supply. Throughput is enhanced by a digital multi-channel analyzer (D-MCA) and optimized control systems. Operation is supported by the ZSX Guidance software platform, which facilitates calibration, data management, and includes scheduling functions to automate measurement sequences.
