A method for the measurement of organically bound tritium (OBT) in marine biota has been developed using a combustion device designed with three independent temperature control zones and a two-stage intake mode to ensure full combustion of samples. The versatility of the combustion device and combustion water recoveries were tested on nine different types of marine biota, with recoveries varying from 85.15% to 92.67%, with an average of 89.4 ± 11.34%. This indicates that our developed combustion method (combustion program and apparatus) provides stable results. Finally, the OBT activity of the marine samples measured varied from 1.88 to 12.9 Bq/L, with an average of 5.61 ± 3.21 Bq/L.

一种基于改进的管状燃烧系统的海洋生物中有机bound的测定方法。

已经开发出一种使用燃烧装置测量海洋生物中有机结合tri（OBT）的方法，该燃烧装置设计为具有三个独立的温度控制区和两阶段进气模式，以确保样品完全燃烧。在九种不同类型的海洋生物上测试了燃烧装置的多功能性和燃烧水的回收率，回收率从85.15％到92.67％不等，平均为89.4±11.34％。这表明我们开发的燃烧方法（燃烧程序和设备）可提供稳定的结果。最后，所测海洋样品的OBT活性在1.88至12.9 Bq / L之间变化，平均值为5.61±3.21 Bq / L。
