| Short description: |
The Field Portable X-Ray Fluorescence (FPXRF) analyser is a portable analytical instrument for determining metal and metalloid concentrations in soils and other media (e.g. paint, alloys); producing a display of the ‘total’ metal and metalloid concentrations.

| Long description: |
The cost of sample analysis often compromises the extent of field sampling, which may increase the uncertainty regarding the estimation of contaminant extent and variability across a site. All sites do not need the same intensity and quality of data. This is determined by the cost of getting it wrong, which is low at a site in a low risk setting but potentially high at a site in a high risk setting.
Assessment of the ‘total’ metal and metalloid content of a soil is traditionally performed using an aqua regia or hydrofluoric acid (HF) digestion followed by Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) or Atomic Absorption Spectrometer (AAS) analysis, which are relatively time-consuming and expensive methods of analysis. X-ray fluorescence (XRF) is more costeffective as it is carried out on a dried and ground sample and does not involve digestion of the soil material. However, this method still requires the removal of the sample to a laboratory.
