Selenium determination in volcanic soils by ICP-QMS: influence of reaction cell pressurization and methanol addition on the occurrence of spectral interferences†
Abstract
Accurate determination of selenium in soils is a critical issue in geochemistry, because Se has a narrow range between dietary deficiency and toxic concentrations. However, its determination is difficult as Se commonly occurs at low levels. Se measurements by
