CAPABILITIES OF DOUBLE FOCUSING MAGNETIC-SECTOR ICP-MS FOR THE DETERMINATION OF TRACE-ELEMENTS IN BODY-FLUIDS (BLOOD, BLOOD-SERUM, URINE) AT THE EXAMPLE OF CONTROL MATERIALS

The capability of double focussing magnetic sector inductively coupled plasma mass spectrometry (HR-ICP-MS) for the determination of trace e lements in different body fluids was investigated in commercially avai lable control materials. The elements included in this study were: Al, As, Cd, Cr, Co, Cu, Hg, Mn, Ni, Pb, Sb, Se, Tl and Zn, Sample prepara tion, instrument stability and the results, which are in very good agr eement to the given values, are presented and discussed.
