Abstract

The capability for Accelerator Mass Spectrometry (AMS) to perform submilligram 14C measurements has considerable implications for environmental carbon research, especially for tracer studies of low concentration carbonaceous aerosols in remote regions. In the present investigation it was possible to perform reliable 14C AMS measurements with carbon samples in the mass range from 30 to 60 υg. The latest findings of a pilot study of carbonaceous aerosols extracted from individual snow samples are presented. The material was collected within a 36-hour period at the Austrian high-altitude research station Sonnblick (3105 m). Significant variations of the 14C content were observed within this period.
