“…To examine potential effects of inhomogeneous sample composition or incomplete chemical separation on the determination of 10 Be and 26 Al, the follow up mass scans were used on the LE magnet after the routine AMS measurement to evaluate the effectiveness of the physical and chemical sample treatment and their possible impact on the AMS analysis results. For instance, it has been found that the 10 Be current reduction in AMS measurement was a function of the BeO/TiO 2 molar ratio (Kameník et al 2023b).…”

The first accelerator mass spectrometry (AMS) laboratory in the Czech Republic has been established and put into routine operation in February 2022. Here we briefly describe the facilities available, namely a 300 kV multi-isotope low-energy AMS system (MILEA) capable of determination 10Be, 14C, 26Al, 41Ca, 129I, isotopes of U, especially 236U, Pu and other actinoids, and accessories for 14C measurements, which include a gas interface system, a preparative gas chromatography system for compound-specific radiocarbon dating analysis, and an isotope-ratio mass spectrometer. The first results achieved for separation and measurement of the above radionuclides (except for 41Ca) are also reported, with the main focus on 14C measurements. A specimen breakdown of 729 graphitised samples analysed for 14C so far is presented, as well as a proof of measurement stability of the MILEA system obtained by analysis of radiocarbon standards and analytical blanks. For the other radionuclides, well proven or novel procedures for sample preparation and measurement are presented.
