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

Abstract

Traceability is a term that is heavily debated world-wide in the analytical chemistry community. An attempt was made to obtain SI-traceable Cu concentration in the candidate reference material MURST-ISS A1 Antarctic sediment. The Antarctic sediment was sampled and processed into a homogeneous and dried powder. The analytical approach used was isotope dilution (ID) combined with inductively coupled plasma mass spectrometry (ICP-MS). Digestion occurred using microwave power and separation by ion exchange chromatography. A detailed interference study was performed. For this purpose the samples were also measured using a high resolution ICP-MS with resolution setting 3000. A prerequisite for traceability is a detailed uncertainty budget. This was performed according to the EURACHEM and International Standardisation Organisation (ISO) guidelines. The uncertainty budget takes into account all possible sources of uncertainty yielding an expanded uncertainty.
