HDXRF Helping Law Enforcement Crackdown on Illegal Mining
2 Feb 2019Illegal mining operations in Indonesia cost the country $6.1B per year in lost tax revenues and license fees. The Indonesia Police Laboratory (Puslabfor) uses HDXRF technology in forensic investigations targeting unlicensed gold, silver and other precious metal mining on public and private lands. Over the past 2 years, hundreds of rock, soil and sludge samples from over a dozen potential sites have been surveyed to identify precious metal and other elemental content. Using this new forensic tool, Puslabfor can link seized materials to specific mining sites making it easier to disrupt illegal mining.

Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.
