Determination of trace elements in a marine reference material of lobster hepatopancreas (TORT-1) using inductively coupled plasma mass spectrometry

Abstract

Sixteen elements (V, Cr, Mn, Fe, Ni, Co, Cu, Zn, As, Se, Sr, Mo, Cd, Sn, Hg and Pb) were determined in acid digests of the marine reference material TORT-1 using inductively coupled plasma mass spectrometry. Accurate results were obtained for most elements although some signal suppression was observed which was easily overcome by dilution of the samples. Corrections were made for interferences arising from chloride in the samples using isotope ratios of ³⁵Cl and ³⁷Cl.
