Features and Benefits

Maximum sensitivity for sulfur and chlorine

The new thin window vanadium anode X-ray tube, specifically designed and manufactured by Malvern Panalytical, ensures high quality and sensitivity. The selection of vanadium as anode material is ideal for the accurate quantification of sulfur and chlorine without interference of possible line overlaps in the XRF spectrum, leading to more reliable and accurate results.

Maximum sensitivity for sulfur and chlorine

No need for helium gas

Epsilon 1 gives you precise and accurate data with minimal sample preparation and running costs. With the high sensitivity of the excitation and detection components, you don’t need helium gas to achieve compliant ISO 13032 results. The air pressure and temperature sensors in the instrument, combined with advanced software algorithms, make every measurement result stable and independent of the environmental conditions. This innovation keeps the total running cost to a minimum.

No need for helium gas

Self-contained system

A built-in computer running Microsoft Windows 10 with a 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 use of standard computer peripherals for extended use, application development and seated operator.
Easy communication

Spillage protection

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

Key Applications

This instrument configuration is designed and manufactured for petrochemical applications, specifically for the refineries where sulfur and chlorine are critical elements.

Epsilon 1 is in compliance with many sulfur related international test methods for ED-XRF instruments, like:

ISO 13032
ASTM D4294
ISO 8754
ISO 20847
IP 336
IP 496

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
  • Extended 15-month warranty period
