Summary: | We describe a new innovative drill core scanner that semi-automatedly
analyses drill cores directly in drill core trays with X-ray fluorescence
spectrometry, without the need for much sample preparation or operator
intervention. The instrument is fed with entire core trays, which are
photographed at high resolution and scanned by a 3-D profiling laser.
Algorithms recognise the geometry of the core tray, number of slots,
location of the drill cores, calculate the optimal scanning path, and
execute a continuous XRF analysis of 2 cm width along the core. The
instrument is equipped with critical analytical components that allow an
effective QA/QC routine to be implemented. It is a mobile instrument that
can be manoeuvred by a single person with a manual pallet jack. |
