Assessing extent-of-equivalence of Chinese and Russian certified reference materials of plants using data of mass spectrometry with inductively coupled plasma

Abstract

A method for studying the adequacy of CRM's compositions ofplants using aggregative assessment based on exploratory data analysis was proposed. It combines for each analyte such statistical estimates as adequacy of calibrations (Fischer's criterion) and quality of results of the analysis (relative bias - RB). The value of RB should not exceed ±10 % (professional criteria). This method clearly and compactly reflects the adequacy (or inadequacy) of the investigated CRM's compositions. The extent-of-equivalence of the compositions of the Chinese and Russian CRMs on data of mass spectrometry with inductively coupled plasma (MS-ICP) were confirmed by the aggregative assessments.
