Analyzing directly on the face provides valuable information for managing excavation. Even in a high grade situation such as percentage concentrations of Molybdenum (Mo), a handheld XRF analyzer can be used. Typically XRF analyzers are designed and calibrated for trace level elemental analysis. However, if necessary, custom calibrations provide the ability to analyze high grade material or diverse matrices accurately and precisely. Typically, analyzing 10 to 15 samples with the XRF and sending these exact samples to the lab to create a calibration curve is all that is required to dial in your XRF for high grade material while still maintaining the ability to analyze trace elements. With the option of using FP, site specific calibrations or Compton Normalization, your instrument is prepared to tackle any application.
What is unique about XRF analysis in the instrumentation world is that they actually provide an estimate of the error with each reading. The longer the analysis time the more precise the analysis will be. The instrument displays both the analysis and an estimate of the standard deviation allowing the operator to continue the measurement to a desired precision. With this type of data available at the mine face, you save time and money as well as provide yourself the ability to guide operations with confidence. Arm yourself with a handheld XRF Analyzer now!
