Fully Integrated X-Ray Fluorescence Spectrometer Epsilon 5 from PANalytical

A fully integrated X-ray fluorescence (XRF) spectrometer, the Epsilon 5 combines advanced elemental excitation capabilities with sophisticated instrument control and analytical software. Epsilon 5 provides high-performance trace element analysis for industry, research and development applications, as well as being a cost-effective option for commercial analytical laboratories.

Key Features

The key features of the Epsilon 5 are:

  • The Epsilon 5 in a novel high-resolution energy dispersive X-ray fluorescence spectrometer specifically designed to deliver excellent sensitivity and precision.
  • Combining optimized Cartesian-geometrical design for lower backgrounds and extended K line excitation 100kV X-ray capability technology, making the Epsilon 5 a powerful instrument. The result is superior and often shows sub-ppm detection limits for mid to heavy elements (Fe – U).
  • Epsilon 5 is excellent while measuring medium to heavy elements. This is due to an improved X-ray excitation design. The K-line of any element by definition is the optimal spectral line to measure because of its superior sensitivity and reduced spectral interference.
  • The Epsilon 5 combines high excitation voltages up to 100 kV, with a matching 100% efficient Ge solid-state detector.
  • A comparison with typical WDXRF systems reveals the Epsilon 5 has superior performance for elements ranging from molybdenum to the rare earth elements.
  • The Epsilon 5 demonstrates very low sample heating or X-ray damage due to a combination of low power and polarized (Cartesian geometry) optics.
  • The absence of sample heating implies that delicate organic samples, foils and filters can be measured repeatedly without inflicting any damage.
