Determination of 36 elements in plant reference materials with different Si contents by inductively coupled plasma mass spectrometry: Comparison of microwave digestions assisted by three types of digestion mixture

Abstract

Silicon concentrations were determined in twelve plant reference materials. Plant materials were digested in three types of digestion blends (HNO3+H2O2, HNO3+H2O2+HF+H3BO3 a v HNO3+H2O2+HBF4) in parallel.

Concentrations of 36 elements were determined and
