  • Establishing a SI-traceable copper concentration in the candidate reference material MURST ISS A1 Antarctic sediment using isotope dilution in combination with inductively coupled plasma mass spectrometry

Abstract

This paper describes an attempt to obtain a SI-traceable value for the copper (Cu) concentration in the candidate reference material MURST-ISS A1 Antarctic sediment. The material was processed into a homogeneous and dried powder. The analytical method used was isotope dilution (ID) combined with inductively coupled plasma mass spectrometry (ICP-MS). Microwave pressurised digestion and copper separation by ion exchange chromatography were used. A detailed uncertainty budget (prerequisite for traceability) was performed according to the ISO/BIPM guidelines. The uncertainty budget takes into account all possible sources of uncertainty (type A and type B) yielding an expanded uncertainty. The certified value for Cu concentration is c(x)=86.7 nmol/g with an expanded uncertainty U=4.9 nmol/g (coverage factor k=2).
