HD Rocksand is lightweight, portable, easy to use, and complies with ASTM D8064 and EPA 6200.
HD Rocksand offers much more than simple screening. With best-in-class limits of detection, it delivers analysis below regulatory limits of over 35 elements. HD Rocksand is lightweight, portable, easy to use, and complies with ASTM D8064 and EPA 6200. This instrument is powered by HDXRF technology which uses Doubly Curved Crystal (DCC) optics to eliminate the scattering background from the x-ray source and reduce interferences that prevent low levels of detection of heavy metal contamination.4
HDXRF is an elemental analysis technique which uses XOS’s patented Doubly Curved Crystal (DCC) optics to enhance measurement sensitivity, precision, and accuracy. Multiple optics capture x-rays from a divergent x-ray beam. The optics redirect several select and monochromatic energy beams to focus intensely on the sample. By using focused monochromatic excitation beams in three different energy regions, HDXRF is able to eliminate scattering background and reduce interferences that hinder measurement sensitivity, repeatability, and speed. The diagram at the bottom right shows the basic configuration of HDXRF and the use of optics to create monochromatic excitation.
