Elemental excellence

X-ray fluorescence spectrometry (XRF) is capable of elemental analysis of a wide range of materials, including solids, liquids and loose powders. Designed to meet the most demanding process control and R&D applications, the Zetium XRF spectrometer leads the market in high-quality design and innovative features for sub-ppm to percentage analysis of Be to Am.

Building on years of experience and success with our extensive analytical X-ray portfolio, Zetium represents a revolutionary step in materials analysis. The platform embodies SumXcore technology – an integration of WDXRF, EDXRF and XRD. This unique combination of possibilities puts Zetium in a class of its own with respect to analytical power, speed and task flexibility in multiple environments.

The Zetium is equipped with the latest version of our SuperQ software, including our Virtual Analyst that enables even non-expert users to easily set up applications. A wide range of additional software modules is available for specific analysis, such as standardless analysis, trace elements in geology, matrix corrections in oils and analysis of thin films.

Dedicated industry editions of the Zetium XRF spectrometer are offered for specific industries: cement, minerals, metals, petrochemicals and polymers & plastics. The Ultimate edition configuration meets the most demanding requirements regardless of industry. The modular design of the Zetium platform allows for task-oriented performance enhancements through various packages. Malvern Panalytical offers a range of integration solutions; from a simple interface with sample preparation equipment, to full automation projects integrating several analytical instruments in a single container laboratory.
