Analytical Package Description

Laboratory: Barringer

Barringer (National Geochemical Reconnaissance), lake sediment; atomic absorption spectroscopy (8 elements: Zn, Cu, Pb, Ni, Co, Ag, Mn, Fe + Cd; air acetylene, decomposition: 4HCl 1HNO3) + atomic absorption spectroscopy (arsenic, antimony; hydride evolution -1g and 6ml conc) + atomic absorption spectroscopy (molybdenum, vanadium; nitrous oxide) + atomic absorption spectroscopy (mercury; cold vapour) + colorimetry (tungsten) + LOI at 500°C, ion-selective electrode (fluorine) + neutron activation-delayed neutron counting (uranium)
