Open data / Characterisation
Nanomaterial characterisation
A small, citable schema for facts buyers already ask for — purity, Raman G/D, form, diameter ranges — without pretending every CoA lives on this site. Listings on nanoMani still use open-ended specs; this dataset is the shared vocabulary beside them.

Illustrative example records for schema exercise and tooling. Not supplier certifications and not lot-verified CoAs.
What this is not
- Not a substitute for a supplier CoA or SDS for a real purchase.
- Not a fixed column set forced onto every listing — product specs stay open-ended (see how it works).
- Not legal advice. For reading a CoA, start with how to read a nanomaterial certificate of analysis.
