This award provides 50% funding for the development of chromatography and vacuum systems that will be installed and operated in the Institute of Arctic and Alpine Research at the University of Colorado. The University is committed to providing the remaining funding required. The equipment will allow specific organic components such as humic acids, lipids, and amino acids to be isolated from small (50- 300 microgram) samples for 14C dating using accelerator mass spectrometry.

该奖项为开发层析和真空系统提供50%的资金，这些系统将在科罗拉多大学北极和阿尔卑斯山研究所安装和运行。该大学承诺提供所需的剩余资金。该设备将允许从小样本(50-300微克)中分离特定的有机成分，如腐植酸、脂肪和氨基酸，以便使用加速器质谱仪进行14C测年。
