Epsilon 1

Small, powerful and portable XRF analyzer

The Epsilon 1 is a fully integrated energy dispersive XRF analyzer consisting of a spectrometer, built-in computer, touch screen and analysis software. Powered by the latest advances in excitation and detection technology the Epsilon 1 is a star performer in the low-cost benchtop instrument class.

Epsilon 1 produces fast, cost-effective, precise and accurate data with minimal operator dependence and sample preparation. The total running cost is therefore much lower than other analytical techniques such as AAS, ICP and wet chemical methods that are costly and also require a dedicated skilled operator. 

The Epsilon 1 is a portable and safe alternative to a handheld xrf analyzer or xrf gun. Read our five reasons why you should consider an Epsilon 1 over a handheld.

Robust and flexible quantification

Epsilon 1 can be calibrated using reference materials that match the composition of the routine samples. These dedicated calibrations result in accurate data with high precision. Epsilon 1 can be calibrated for a wide variety of industry applications. 

Epsilon 1 is a star-performing benchtop XRF instrument for the analysis of major, minor and trace elements from sodium to americium, across the periodic table.

Enhanced data security

The Enhanced Data Security option for the Epsilon system software helps you strengthen your audit trail, minimize the risk of error, and prove that your XRF instrument is working as expected. Capabilities include advanced user management, action logging, and data protection.


Non-destructive analysis

The measurements are carried out directly on the sample itself with little to no sample preparation. Since XRF is a non-destructive technique, the sample can also be measured subsequently by other analytical techniques, if required.
Non-destructive analysis

Maximum sensitivity

The thin window Ag anode X-ray tube, designed and manufactured by Malvern Panalytical, ensures high quality and sensitivity. The 50 kV X-ray tube and generator is ideal for exciting heavier elements, resulting in faster analysis times and higher accuracy.
Maximum sensitivity

Easy communication

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

Easy communication

Atmospheric variations

Low-energy X-ray photons characteristic of sodium, magnesium, aluminum, silicon, phosphorus and sulfur are sensitive to air-pressure and temperature variations. Built-in temperature and air-pressure sensors compensate for these atmospheric variations, ensuring excellent results whatever the weather.

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.

Guided Smart Install

When correctly installed your new Epsilon 1 will give you reliable analysis results. Installing an Epsilon 1 is straightforward: unpack the system, plug it in and follow the instructions, which we will guide you through. Finally, a simple radiation test completes the installation and confirms that your system is working safely. Yes, it is that easy to start using your Epsilon 1. And, more importantly, you can rest assured that your system is supplied with the necessary safety certification.
Smart install ensures you can get new instruments up and running even when unexpected circumstances or remote locations prevent an engineer from accessing your facility. For the Epsilon 1, we offer a guided  smart installation, enabling you to install the system yourself and maintain the integrity of the instrument and its safety certification.

The advantages of guided smart install:

  • Get up and running fast
  • Save on installation costs
  • Install the system when it suits you
