ZSX Primus IV/IVi

The Rigaku ZSX Primus IV/IVi XRF spectrometers are high power (4kW) sequential WDXRF instruments that combine high-throughput with industry-leading light element sensitivity and resolution. Available in tube above and tube below optical configurations, they use X-ray sources that feature excellent long-term stability and reliability. This makes them ideal for the most demanding industrial and academic chemical analysis applications e.g. mining and minerals, cement, alloys, liquids, plated metals etc.

ZSX Primus IV – Tube Above Configuration

Rigaku’s unique tube-above optical configuration virtually eliminates the possibility of debris being deposited on the X-ray source or detector. This ensures accuracy of measurements as well as avoiding unwanted maintenance making it the ideal choice for pressed powders and liquids.

ZSX Primus IVi – Tube Below Configuration

The ZSX Primus IVi utilises a conventional tube-below optical configuration. This configuration has allowed Rigaku to package the system into the smallest footprint in the industry and is ideal for fused beads, allots, plated metals and liquids.

High-Throughput Analysis and Automated Sample Handling

The system has been optimised for high-speed, automated analysis, making it ideal for industrial applications requiring rapid turnaround times. Improved mechanical and electronic designs have resulted in reduced dead time and higher sample throughput. Increased throughput speeds are also aided by a Digital Multi-Channel Analyzer (D-MCA) system that provides high-speed processing for high count rates culminating in improved analytical precision.

Light Element Performance

The Rigaku ZSX Primus IV/IVi also offers exceptional light element detection limits thanks to a 30µm Be window on the X-ray tube, the thinnest commercially available as well as especially developed analyzer crystals, with dedicated 2d values, to capture light element wavelengths

For ultra-light elements (Be – O) and light elements with low energy X-ray emissions (F – Al), the degree of vacuum greatly impacts X-ray intensity. The APC (Automatic Pressure Control) enables steady state vacuum conditions to be maintained and facilitates reproducible X-ray intensities for these elements.

More Consistent Analyses

It also features Rigaku’s optical system that suppresses signal variations that are produced because of changes in the distance between sample and detector due to uneven surfaces etc.

Point Mapping

The ZSX Primus IV/IVi also allows you to perform point mapping. Using a high-resolution camera, you can easily zoom in on a specific feature of interest and carry out chemical analysis which is ideal for inhomogeneous samples such as minerals or alloy inclusions.

Improved SQX Software

Through continuous refinements, Rigaku’s SQX analysis gets easier to use. It is a highly accurate method for determination of the elemental composition of your sample based on standardless FP analysis.

ZSX Guidance Software

ZSX Guidance supports you in all aspects of XRF measurement and data analysis. Common to all Rigaku WDXRF spectrometers, ZSX guidance puts even the most complex measurements and analyses in the hands of any user while facilitating all your routine and scheduled measurements.
