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.
