Description: Our research requires determinations of total elemental concentrations of forest soils. The lack of certified forest soil reference materials led us to develop internal reference samples. Samples were collected from three soil horizons (Oa, B, and C) at three locations having forested, acidic soils similar to those we commonly analyze. A shatterbox was used to homogenize the nine samples. The Radiation Laboratory of the University of Massachusetts, Lowell completed neutron activation analyses (NA) on our samples. Our laboratory performed five digestion procedures: microwave [nitric acid (HNO3), hydrochloric acid (HCl), fluoboric acid (HBF4), hydrogen peroxide (H2O2)], block [sulfuric acid (H2SO4), selenious acid (H2SeO3), and H2O2], hot plate ([hydrofluoric acid (HF) and perchloric acid (HClO4)], and flux [lithium borate (Li2BO2) and lithium treborate (Li2B4O7)].
