Description

In Accelerator Mass Spectrometry (AMS) laboratories, chemical pretreatment is vital for reducing sample contamination and improving the accuracy of the data. Specifically, in radiocarbon dating with AMS, chemical pretreatment is used to eliminate carbonates and humic acids, leading to more precise measurement results. This technique has been traditionally method applied to ancient archaeological and geological samples and is now also used for environmental samples. This study evaluates three distinct chemical pretreatment methods for AMS and the findings of the corresponding measurements are presented in this paper.
