摘要：
The Accelerator Mass Spectrometry activities at Uppsala University include a group dedicated to the biomedical applications, involving natural level samples, as well as C-14-labeled substances requiring separate handling and preparation. For most applications sufficient sample amounts are available but many applications are limited to samples sizes in the mu g-range. We have developed a preparation procedure for small samples biomedical applications, where a few mu g C can be analyzed, albeit with compromised precision. The latest results for the small sample AMS method are shown and some of the biomedical activities at our laboratory are presented. (C) 2015 Elsevier B.V. All rights reserved.
