英文摘要	The determination of trace lead in a CaCO3 matrix by isotope dilution coupled anion-exchange and quadrupole-based inductively coupled plasma-mass spectrometry was established. The matrix of CaCO3 seriously affected the determination by clogging the cones of the instrument was removed by the anion-exchange resin column. Effects such as dead time, mass bias, dwell time and the amount of isotopic agent spiked were discussed and corrected. The detection limit estimated by 3x standard deviation of the procedure blank was 2.94ngg-1. The results indicated that the lead concentration in all samples tested was far less than 3%, the legislated limit. The recovery mostly ranged from 90 to 110%. The relative standard deviation was found to be <1%. © 2003 Elsevier B.V. All rights reserved.
