Corrections for Contamination Background in AMS 14 C Measurements

  • T. A. Brown J. R. Southon

Abstract

Measurements of 14C/13C ratios were made on samples of Oxalic Acid and 14C “dead” materials spanning the mass range from 10 μg to ~1 mg. These measurements have allowed the determination of both the amount, and the 14C content, of the contaminant carbon introduced during sample processing in our laboratory. These data were used to correct measured 14C/13C… (More)
