Abstract

Ice from polar regions is an archive of climate. The climate can be reconstructed by physical and chemical data back to about 900,000 years. The analysis of element signatures in ice cores yields information about the strength of sources and transport mechanisms for aerosols in the paleoatmosphere as well as about the paleovolcanism.When analysing element concentrations / signatures in polar ice cores directly by laser ablation ICP-MS, frozen multielement standards for calibration were used so far (Reinhardt et al., 2001, 2003; Dick et al. 2003). It is known and obvious that problems occur when solid particle horizons inside ice cores are analysed and calibrated using frozen multielement standards. To improve this, a method to prepare standards with homogeneously distributed particles was developed. 7 standards with varying dust concentrations were prepared from the NIST 1648 CRM and afterwards analysed. Satisfying results were obtained.
