Abstract
Marine biological reference material LUTS-1, lobster heptopancreas, was analyzed for elemental homogeneity using graphite furnace atomic absorption, anodic stripping voltammetry, and neutron activation analysis. Analysis of samples taken from 12 bottles of LUTS-1 bottled on two different days showed no statistical differences at the 95% confidence level for within-bottle variance for a large number of elements. Differences were observed for between-day variances for aluminum, iron, cobalt, sodium, chlorine, bromine, and iodine, but not at a level sufficient to affect utility as a reference material. Keywords: neutron activation analysis, graphite furnace atomic absorportion spectroscopy, anodic stripping voltammetry, elemental analysis, marine biological reference material.
