ICOS ATC 14C Release analysed by ICOS CRL, Hyltemossa (150.0 m), 2015-09-23–2022-11-24

The ICOS Central Radiocarbon Laboratory (CRL) central task is the high-precision measurement of the ¹⁴C content in atmospheric CO₂. The ¹⁴CO₂ activity is determined for grab samples (flask) as well as for two-week integrated ambient air samples. Two ¹⁴CO₂ analytical techniques are applied in the CRL: Accelerator Mass Spectrometry (AMS) in collaboration with the CEZA laboratory in Mannheim, Germany (Lux, 2019), and Low-Level gas proportional Counting (LLC) (Kromer & Münnich, 1992). The comparability of both measurement techniques is continuously monitored and was documented in Hammer et al. (2017)

ICOS中央放射性碳实验室（CRL）的核心任务是对大气二氧化碳中的¹⁴C含量进行高精度测量。实验室对抓取样品（集气瓶）以及两周综合环境空气样品进行¹⁴CO₂活性测定。在CRL中，应用了两种¹⁴CO₂分析技术：与德国曼海姆的CEZA实验室（Lux, 2019）合作进行的加速器质量光谱法（AMS），以及低水平气体比例计数法（LLC）（Kromer & Münnich, 1992）。这两种测量技术的可比性得到持续监控，并在Hammer等人（2017）的研究中进行了记录。
