About us

The Czech Radiocarbon Laboratory with the international code CRL was established in 2004 as a joint workplace of the Nuclear Physics Institute of the Czech Academy of Sciences and the Institute of Archeology of the Czech Academy of Sciences, Prague.

Since 2013 we have been conducting radiocarbon dating and carbon-14 analysis using the Accelerator Mass Spectrometry (AMS) method, since 2022 using our own MILEA (Multi-Isotope Low-Energy AMS) instrument from the Swiss company IonPlus. MILEA is a medium-sized device with a working voltage of up to 300 kV.

Other laboratory equipment: Preparative gas chromatograph Agilent 8890 with FID detector and Gerstel fraction collector for molecular-specific radiocarbon analysis; time-of-flight (TOF) mass spectrometer from Leco for screening and quantification of target compounds in complex matrices; sector spectrometer (ThermoFisher Scientific) for measuring stable isotope ratios connected via ConFlow IV gas interface with SmartFlash elemental analyzer.

Services: Radiocarbon dating and carbon-14 analyses, determination of stable isotope ratios (most often 2H/1H, 13C/12C, 15N/14N, 18O/16O and 34S/32S), consultations and interpretation of results.

Head of the laboratory: Ivo Světlík (


The laboratory was supported by OP RDE, Ministry of Education, Youth and Sport of the Czech Republic, under the project "„Ultra-trace isotope research in social and environmental studies using accelerator mass spectrometry“, Reg. No.CZ.02.1.01/0.0/0.0/16_019/0000728.
