The Institute of Hydrology and Environmental Geology (IHEG), CAGS organized a research group engaged in radionuclides analysis and dating by AMS in 2015, then purchased its first multi-element AMS facility (1MV, HVEE) in 2017. Unfortunately, this facility has not been installed yet. The 10Be and 26Al sample preparation laboratory spent the better part of 2020 establishing pretreatment protocols, and streamlining sample processing, included optimizing extraction and purification of quartz, ion exchange chromatography methods, minimizing backgrounds. Here, we present an overview of sample processing protocols and results from measured standards, reference, and blank materials.
