Maximum sensitivity

The thin window Ag anode X-ray tube, designed and manufactured by Malvern Panalytical, ensures high quality and sensitivity. The selection of Ag as anode material is ideal for the accurate quantification of phosphorus and sulfur without interference of possible line overlaps in the XRF spectrum, leading to more reliable results. The 50 kV X-ray tube and generator is ideal for exciting higher-energy elements like zinc, resulting in faster analysis times.
Maximum sensitivity

Self-contained system

A built-in computer running Microsoft Windows 7 with powerful CPU and 120 GB hard drive ensures flexibility to store and handle thousands of results. The high-resolution, 10.4” LCD touch screen is ideal for easy walk-up operation.
Self-contained system

Easy communication

USB and network connections for standard computer peripherals support extended use, application development, and seated operator.

Easy communication

Spillage protection

A spillage protection foil is in place to shield the delicate heart of the system. In case of spillage, the foil can be replaced easily by the operator.

Epsilon software

Epsilon software is the XRF analysis software platform that is used with PANalytical’s range of Epsilon 1 and Epsilon 4 benchtop EDXRF systems.

Epsilon software


The software provides a rapid, simple and non-destructive means of analyzing coatings, surface layers and multi-layered structures.


Omnian software enables users to achieve the best possible analysis when dedicated methods or certified standards do not exist.



A FingerPrint software module combined with an Epsilon EDXRF system is ideal for material testing when analysis speed is important but the actual composition is not of interest.
