TL;DR: RMNS produced by state-of-the-art techniques are currently available for global use to improve the comparability of nutrients data in the open ocean and, as discussed here, are reliable candidates to be used for certified reference materials.

TL;DR: An apple certified reference material for the analysis of pesticide residues was issued by the National Metrology Institute of Japan and the values of target pesticides were obtained by isotope dilution mass spectrometry.

TL;DR: A soybean certified reference material for pesticide residue analysis was developed by the National Metrology Institute of Japan and demonstrated that the relative standard uncertainties due to the inhomogeneity and the instability for an expiry date of 55 months were 1.89-4.00% and 6.65-11.5%, respectively.

TL;DR: These are the first green onion and cabbage powder certified reference materials in which organophosphorus and pyrethroid pesticides are determined.

TL;DR: In the 2008 I/C study as mentioned in this paper, a set of six samples was distributed to each of 58 laboratories in 15 countries around the globe, and results were returned by 54 of those laboratories (15 countries).
