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）的核心任务是进行大气二氧化碳中碳-14含量的高精度测量。该实验室对抓取样本（烧瓶）以及两周集成环境空气样本进行碳-14二氧化碳活度的测定。在 CRL 中应用了两种碳-14二氧化碳分析技术：与德国曼海姆的 CEZA 实验室合作进行的加速器质谱法（AMS）（Lux, 2019），以及低水平气体比例计数（LLC）（Kromer & Münnich, 1992）。两种测量技术的可比性持续得到监控，并在 Hammer 等人（2017）的研究中得到了记录。
