AbstractAn intralaboratory determination of total Sn in three National Research Council of Canada reference materials, i.e., estuarine sediments BCSS-1 and MESS-1 and lobster hepatopancreas TORT-1 was undertaken. Samples were solubilized by acid mineralization and analyzed by stable isotope dilution inductively coupled plasma mass spectrometry, direct solution injection graphite furnace atomic absorption spectrometry (GFAAS), and hydride generation-GFAAS. The materials were homogeneous at the 500 mg subsample size. Good agreement was obtained amongst the results from the three instrumental methods of analysis. Certified values of total Sn in these materials are 1.85 ± 0.20 μg/g in BCSS-1, 3.98 ± 0.44 μg/g in MESS-1, and 139 ± 11 ng/g in TORT-1. The above uncertainties represent 95% tolerance limits for an individual (500 mg) subsample.
