The organic reference material is intended for δ¹⁸O oxygen isotopic calibrations by using TCEA technique [1]; the δ¹³C value is given for information purpose only. Use of IAEA-602 for δ¹³C carbon isotopic analysis by combustion technique is not recommended as it is enriched in ¹⁷O and ¹⁸O, so its ¹⁷O/¹⁸O ratio no longer reflects that of natural terrestrial materials [2]. Values [1, 2] are reported on the VSMOW scale and VPDB scale correspondingly.

(R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
[1] VSMOW scale
[2] VPDB scale
