With chemical safety, substance identification is the first step.
One must conclude, therefore, that substance identification is a neglected and misunderstood domain in analytical toxicology.
Although substance identification is a key factor in analytical toxicology, it is amazing that the subject is receiving very limited and often inappropriate attention.
The formulation of the product, if it is available, is a good starting point for substance identification.
Since a reliable substance identification requires two powerful and independent analytical methods, at least the application of NMR techniques seems to be essential.
The use of this band has been proposed for high-speed data links, automotive radar, radar imaging, security screening, substance identification, and non-destructive testing among others [1 3].
The certainty of the substance identification is rated with respect to the performance of the applied analytical techniques, to the concordance of results achieved by different methods, and to the traceability of the analytical procedure.
In the project on Substance Identification of Nanomaterials (RIP-oN 1), no consensus between the stakeholders was reached on whether parameters like size, shape and surface treatment of a nanomaterial can be regarded as a so-called identifier (changes in parameters trigger a new substance) or 'characterizer' (changes in parameters do not trigger a new substance, but another form of a substance).
ECHA provides a series of guidance documents to assist manufacturers and importers that have to meet different obligations under REACH on, e.g., registration, substance identification, chemicals safety assessment in order to"…facilitate the implementation of REACH by describing good practice on how to fulfil the obligations…" [25] that REACH places on industry.
The category documentation involves questions about substance identification and/or literature reports about clinical effects.
