​​International Chemical Safety Card (ICSC): ICSC_0405_Caffeine

Reference material IAEA-600 is aimed at δ¹³C calibrations by TC/EA technique; its δ¹⁵N is provided for information purpose.

IAEA-600 was prepared by W. Brand and R. Werner, Max-Planck-Institute for Biogeochemistry, Jena, Germany, from commercially produced pure caffeine. Its recommended δ¹³C value was determined in an international calibration [1]. For this reference material the δ¹⁵N value war determined in one laboratory only and therefore is only an information value.

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