产品详细介绍
IAEA-C6 Sucrose Pure Substance
IAEA‑C6 Sucrose (its former name was “ANU Sucrose”) was originally prepared by H.A. Polach, by selecting a batch of 2 tons of cane sucrose, which was sealed in drums (20kg each) to serve as a secondary 14C standard [6] calibrated in relation to NBS Oxalic Acid I (HOxI). The material was originally available from the IAEA, the Australian National University ANU and the University of Arizona at Tucson. The recommended value of this quality control material is the result of the statistical evaluation of an interlaboratory comparison [1, 2].
