Versatile handheld XRF spectrometer with light element analysis


The XL3 SDD mobile X-ray fluorescence spectrometer measures the light elements Mg, Al, Si, P, S, Cl quickly and easily under air. It uses a particularly high-resolution silicon drift detector (SDD) with a large area. Excitation, signal processing and instrument geometry are optimized for this GOLDD (Geometrically Optimized Large Area Drift Detector) technology. This greatly simplifies the detection of the light elements Mg, Al, Si, P, S, Cl. The foldable display allows ergonomic handling and comfortable reading under changing light conditions.

Compared to Si PIN diodes, SDD detectors achieve:

  • Improvement of counting rate by factor 10
  • Enhancement of precision by factor 3
  • With the XL3 SDD model, the critical elements Mg, Al, Si, P, S are already measurable under air (without helium and vacuum).
  • Distinction between pure aluminium and Al, Mg
  • Phosphorus in bronze
  • Even better detection of the elements (Mg, Al, Si, P, S, Cl) in archaeometry.

Areas of application

Typical applications:

  • Mg, Si in aluminium alloys
  • Al in titanium and zinc alloys
  • Al and Si in bronze and magnesium alloys
  • P in bronze
  • Super alloys and special steels
  • Al in Monel K500 and Si in Nitronic 60
  • Si and P in cast iron
  • Si in transformer steel, detection of phosphatings
  • Mg, Al, Si, P in mineral compounds, colour pigments, ceramics, clay, glass.
