Fig. 1 One MV AMS for biological/biomedical applications at the center for AMS (CAMS), Lawrence Livermore National Laboratory (LLNL).²⁷ Reprinted from Int. J. Mass Spectrom., 2002, A new accelerator mass spectrometry system for C-quantification of biochemical samples, T. J. Ognibene, G. Bench, T. A. Brown, G. F. Peaslee and J. S. Vogel, 2002, 218, 255–264, with permission from Elsevier.

Fig. 2 AMS unit, Modern and the working range for bio-¹⁴C-AMS. The Modern indicates the natural level of radiocarbon in living creatures, and it converts to other units like curies, moles, disintegration per minute (dpm). This figure has been reproduced from the Springer publication⁵, J. S. Vogel and K. W. Turteltaub, Adv. Exp. Med. Biol., 1998, 445, 397-410 with kind permission of Springer Science and Business Media.

Fig. 3 The efficiencies of AMS and decay counting as a function of half-life (T_1/2). This figure was reproduced with permission from R. Hellborg and G. Skog, Mass Spectrom. Rev., 2008, 27, 398-427.

Fig. 5 The different graphitization system for bio-¹⁴C-AMS applications (A) catalytic graphitization system,⁴⁵ (B) graphitization system with a flame-sealed borosilicate tube,⁴³ (C) graphitization system with a septa-sealed vial).⁴² These figures were reproduced and minimally edited from the prior publications ^42,43 with permission. Figure (C) was reproduced and edited with permission from T. J. Ognibene, G. Bench, J. S. Vogel, G. F. Peaslee and S. Murov, Anal. Chem., 2003, 75, 2192-2196.

The following references should be included at the end of the following sentence on p. 3349:

The AMS at LLNL uses the C⁴⁺ ion for the 10 MV AMS but uses the C⁺ ion for the 1MV AMS. This process eliminates molecular isobars of ¹⁴C including ¹²CH₂^-, ¹²CD^-, and ¹³CH₁^- because their cationic forms are physically and chemically very unstable.^5,27

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
