Wavelength Dispersive XRF Spectrometer - ZSX Primus 400

Rigaku's unique ZSX Primus 400 sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer was specifically designed to handle very large and/or heavy samples that measure up to 400 mm in diameter, 50 mm in thickness and 30 kg in mass. This system is therefore an ideal solution for analyzing sputtering targets, magnetic disks and multilayer film metrology, or for the elemental analysis of large samples.

XRF with Customized Sample Adapter System

This WDXRF spectrometer is highly versatile in its ability to adapt to specific sample types of various sizes and shapes through the use of optional adapter inserts that are made to order. Additionally, this instrument is also able to adapt to different analysis requirements. With a variable measurement spot whose diameter ranges from 30 mm to 0.5 mm, a 5 step automatic selection and mapping capability with multi-point measurements to check for sample uniformity makes this WDXRF spectrometer a uniquely flexible instrument can dramatically streamline your quality control processes.

XRF with Available Camera and Special Lighting

Optional real-time camera allows the analysis area to be viewed within software, thereby providing the operator with complete certainty and control over the sample being measured and analyzed.

Traditional WDXRF Analytical Capabilities

The same analytical capabilities of a traditional instrument are retained in this "large sample" variant. These capabilities include a high resolution and precision analysis of elements ranging from beryllium (Be) to uranium (U) using WDXRF spectroscopy, as well as samples that are solids, liquids, powders and even thin films that are in the composition sizes ranging from ppm to tens of percent, as well as a wide range of thicknesses from sub Å to mm.

The diffraction peak interference rejection is also available to achieve optimal results for single-crystal substrates. The Rigaku ZSX Primus 400 wavelength dispersive X-ray fluorescence (WD-XRF) spectrometer complies with industry standards SEMI and CE.
