Ultra-Portable Rare Earth Element Exploration


An evolution of the DELTA Premium handheld XRF, the DELTA -50 offers a powerful 4 Watt, 50kV tube coupled with a large area, high resolution SDD. The DELTA -50 is ideal for rapid on-site compositional analysis of rock outcrop, soil, sediment, till, drill cuttings, diamond core and ore grade material. It is the optimal tool for on-site quantification of rare earth elements (REEs) including La, Ce, Pr, and Nd, as well as typical REE pathfinders including Y, Th, and Nb.

The real value arrives in the field where the Geoscientist can now use the realtime, "Instant Geochemistry" delivered by the DELTA to make decisions about site geology. Adapt sampling and mapping programs on-the-spot. Make immediate decisions while maximizing your exploration budget.

The DELTA-50 brings the power of a mobile lab to a handheld system - ruggedized and ultra portable. All DELTA XRF analyzers are engineered for continual use, carrying out thousands of tests per day in some applications, even in extreme environments. Engineered for rugged toughness AND analytical precision - there are no compromises!

Delta Handheld XRF Analyzer
Typical Limits of Detection (ppm)
Y 1-2
Th 2-3
Nb 2-3
Ag 3-5
Cd 2-3
Sn 5-8
Sb 5-7
Ba 20-25
La 30-50
Ce 45-60
Pr 65-100
Nd 75-350
Detection limits are a function of testing time, sample matrix and presence of interfering elements.
Detection limits are estimates based on 1-2 minutes test times and detection confidence of 3o (99.7% confidence).
Interference-free detection limits are intended as guidelines: please contact us discuss your specific application.
