OXFORD INSTRUMENTS - THE EXPERTS IN ANALYSIS 
 
XRF (X-ray Fluorescence) is a proven technique for material analysis in a broad range of industries and applications; from Positive Material Identification, scrap metal sorting, measuring sulfur in oil, analysing coating thickness of metal finishing and metal alloys to quality control in the electronics and consumer goods industry. 
 
Benefits of analysis by XRF include:
  • Minimal or no sample preparation
  • Non-destructive analysis
  • Na11 to U92 analysis, ppm to high % concentration range
  • No wet chemistry – no acids, no reagents
  • Analysis of solids, liquids, powders, films, granules etc.
  • Rapid analysis – results in minutes
  • Qualitative, semi-quantitative, to full quantitative analysis

Laser-Induced Breakdown Spectroscopy (LIBS) is becoming a popular analytical technique, which can potentially measure all elements in the periodic table, in samples of all types (gas, solids, liquids).   A diode focuses laser pulses through the instrument’s nose aperture and generates a high temperature micro-plasma on the surface of the analysed alloy sample.  Microscopic particles of the alloy are extracted from the surface into the plasma where they are atomised and energised.   After this excitation, light that is characteristic of the elemental composition of the metal is emitted and analysed within the spectrometer (optics).   The laser is very powerful but is focused on a point on the sample and causes virtually no sample heating around the test area.
 
 
 
 
 
 

 
​In Optical Emission Spectroscopy (OES) technology, atoms in a sample are excited by energy that comes from a spark formed between sample and electrode.  The energy of the spark causes the electrons in the sample to emit light which is converted into a spectral pattern. By measuring the intensity of the peaks in this spectrum, Oxford Instruments OES analysers identify the quality and quantity of the material composition with uncompromising accuracy. They are ideal for high performance analysis of alloyed and trace elements, nitrogen analysis in duplex steels.
