Multi-element determination in environmental samples by mass spectrometric isotope dilution analysis using thermal ionization - Part I: Pine needles

Abstract

A procedure for multielement analysis using mass spectrometry with thermal ionization and the isotope dilution technique was developed. The analytical procedure was checked by investigating the Standard Reference Material no. 1575 "Pine Needles" supplied by the National Bureau of Standards, USA. The concentrations of the elements Fe, Ni, Cu, Zn, Ga, Rb, Sr, Cd, Tl, and Pb were simultaneously determined in this material. The total amount of ions observed in the mass spectrum originating from the material investigated is discussed. It follows that it might be possible to increase the number of elements determinable simultaneously to 19. © 1986 Springer-Verlag.
