Epsilon 1 is a star-performing benchtop XRF instrument for the analysis of sulfur in fuels according to the latest test methods: ASTM D4294, ISO 20847 ISO 8754, IP496, IP336, and JIS K2541-4. The results of the repeatability test for sulfur are well within the limits set by ASTM D4294, being the most stringent method.



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 sulfur without interference of possible line overlaps in the XRF spectrum, leading to more reliable results.
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 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.
