ZSX Primus400

Sequential Wavelength Dispersive XRF Spectrometer for Large Samples

Elemental analysis of solids, liquids, powders, alloys and thin films

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. Accepting samples up to 400 mm diameter, 50 mm thick and 30 kg mass, this system is ideal for analyzing sputtering targets, magnetic disks, or for multilayer film metrology or elemental analysis of large samples.

ZSX Primus400 Overview

XRF with customized sample adapter system

Having the versatility to adapt to your specific sample types and analysis needs, this WDXRF spectrometer is adaptable to various sample sizes and shapes using optional (made to order) adapter inserts. With a variable measurement spot (30 mm to 0.5 mm diameter, with 5-step automatic selection) and mapping capability with multi-point measurements to check for sample uniformity, this 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. The operator has complete certainty as to what is being measured.

Traditional WDXRF analytical capabilities

All analytical capabilities of a traditional instrument are retained in this "large sample" variant. Analyze beryllium (Be) through uranium (U) with high-resolution, high-precision WDXRF spectroscopy, from solids to liquids and powders to thin films. Analyze wide composition ranges (ppm to tens of percent) and thicknesses (sub Å to mm). Optionally available is diffraction peak interference rejection, for optimal results for single-crystal substrates. Rigaku ZSX Primus 400 wavelength dispersive X-ray fluorescence (WD-XRF) spectrometer complies with industry standards SEMI and CE.
