U of h dating
Active gases, particularly hydrogen, are removed using SAES getters.
This new technique allows further refinement of Geotracks THR methods, providing: (U-Th)/He dating, developed and proven by Professor Ken Farley of Caltech, is based on the accumulation and diffusive loss of Helium produced by alpha decay of Uranium and Thorium impurities within apatite grains.

Aliquots of ~5-30 grains are sealed into stainless steel capsules and then up to 6 capsules are loaded into the furnace sample holders. Ken Farley of Caltech, based on the systematics presented in Farley (2000) and references therein, allows modelling of the (U-Th)/He age expected from any inputted thermal history, in grains of any specified radius.
