IAEA-CH-3 is aimed at δ¹³C calibrations by TC/EA techniques.

IAEA-CH-3 was prepared in 1989 at the IAEA from large batch of cellulose harvested from approximately 40 years old trees originating from Sweden. Processed material was pressed into sheets and initially characterized for ¹⁴C value of IAEA-C3. Three kilograms of these sheets were milled to fine powder, homogenized and characterised for δ¹³C value of IAEA-CH-3. The final calibration of the material was performed in 2004 by a small group of experienced laboratories together with the re-calibration of most of the other organic carbon stable isotope reference materials available at IAEA [1].

(R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
