Documentation, stated plainly
No certificate of analysis is published for any current listing, and nothing on this site implies one. What every listing does carry is the manufacturer's stated purity figure and method, the physical form and the fill size. The purity figure on each listing is the one stated to us by the manufacturer. We have not seen a certificate of analysis for it, we have not measured it ourselves, and no testing has been commissioned in Tyde's own name. Treat it as the manufacturer's claim rather than a verified result, and verify anything your work depends on in your own laboratory.
