Easy to integrate into production processes with standard communication protocols 

Able to measure all valuable elements of interest, including platinum and cerium 

Capable of measuring thin layers with excellent precision

Accommodates a range of roll widths

Unique patented robotic arm that provides optimal distance control by hovering the measurement head over the production line in all directions

Facing the challenges of fuel cell production

With platinum catalysts accounting for more than 20% of your overall fuel cell costs, optimizing catalyst coating through uniform dispersion and consistent layering is essential. And fast, accurate process monitoring is the ideal solution! The Epsilon Xline makes efficient operational control easy, helping you to:  

Minimize your off-specification production  

Save valuable platinum from being wasted  

Produce cost-competitive end-products 

Features

Full in-line automation. Enjoy continuous R2R production thanks to the Epsilon Xline’s seamless integration capabilities, suitable for a range of thin-film and coating applications. 

Simple and safe. The Epsilon Xline is fully X-ray safe and easy to use, unlike handheld or legacy instruments, and delivers highly accurate analytical data. 

A lifetime of experience. Drawing on Malvern Panalytical’s more than 70 years’ experience in elemental analysis, the Epsilon Xline was developed in collaboration with our industry partners to meet their needs of today – and at the same time looking to the industry’s future together. 

Maximized yield. Achieve cost-competitive production with real-time monitoring and no disruption – giving you the direct insights and control you need to get the most out of your operations. 

Optimum materials efficiency. Eliminate inconsistencies, avoid wasting precious materials, and ensure a high-quality product with our industry-standard solution. 

Proven, patented accuracy. Developed and tested with customers, the Epsilon Xline features patented height-correction technology that ensures stable analysis for accurate results. 

Proven technologyElemental analysis within your process

X-ray fluorescence (XRF) is a non-destructive elemental analysis technology that enables in-line monitoring during the coating processes of catalytic membranes – without the need to take samples and without chemical or physical changes.  

The resulting real-time in-line analysis enables the rapid optimization of many process parameters and product properties. 

Highly repeatable and accurate measurements with low maintenance

The proven and robust technology used in the Epsilon Xline and throughout our series of Epsilon instruments is powered by the latest advances in excitation and detection technology. A well-designed optical path, a wide range of excitation capabilities for light and heavier elements, and a fast high-resolution SDD detector system contribute to the power of the Epsilon Xline. These innovations result in highly repeatable and accurate results with low maintenance.
