Purity & Documentation

A Certificate of Analysis is provided with each shipment, reporting appearance, assay, melting point and identity by 19F NMR. The 19F NMR shift confirms the bis(trifluoromethanesulfonyl)imide anion; it does not identify the metal, and confirmation of the metal is available on request. We work to custom specifications, and additional testing can be quoted on request; this may carry additional cost and lead time.
