Abstract

Inductively coupled plasma-mass spectrometry has been used to evaluate contamination of sampling and storage containers designated for use in the determination of minor and trace elements in body fluids. Potential contamination from Al, As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cs, Cu, Hg, Li, Mn, Mo, Ni, Pb, Pd, Pt, Rb, Sb, Sn, Sr, Ti, Tl, U, V, and Zn was evaluated. In general, plastic containers are preferable for sampling for most elements, and EDTA-containing collection tubes for whole blood are to be avoided. Systematic errors due to sampling of blood with stainless steel needles or Teflon catheters, into glass and plastic containers, have been estimated.
