Can it tell you the batch\u2019s purity? Usually that is not its purpose. COAs, SDSs and spectra answer different questions. Knowing which one to read saves you from searching the wrong document.<\/p>\n<h2>Mettre les trois documents c\u00f4te \u00e0 c\u00f4te<\/h2>\n<p>Un COA, ou certificat d\u2019analyse, consigne les tests et r\u00e9sultats d\u00e9clar\u00e9s pour la mati\u00e8re ou le lot identifi\u00e9. Une FDS, ou fiche de donn\u00e9es de s\u00e9curit\u00e9, organise les informations sur les dangers et la manipulation. Les trac\u00e9s analytiques montrent les signaux derri\u00e8re des mesures particuli\u00e8res.<\/p>\n<p>A simple way to choose: \u201cWhat was measured?\u201d points toward analytical results; \u201cHow do I handle this material?\u201d points toward the SDS; \u201cWhat does this peak mean?\u201d needs the plot and method.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/nhdbio.com\/wp-content\/plugins\/nhd-content-refresh\/teaching-images\/t20\/en\/1.png\" alt=\"Figure 1.
