Riferimenti a colore e standard per spettroscopia

I riferimenti di colore e gli standard di spettroscopia vengono utilizzati di routine per monitorare i meccanismi degli spettrometri ottici. Le soluzioni di calibrazione forniscono le letture di base che gli utenti possono confrontare con le lunghezze d'onda e le intensità della radiazione elettromagnetica ottenute dagli strumenti scientifici. Inserendo la soluzione di riferimento, gli utenti possono azzerare le impostazioni per ristabilire il corretto funzionamento ed eliminare l'errore sistematico. Per il controllo qualità, i riferimenti di colore e gli standard di spettroscopia garantiscono che le apparecchiature funzionino correttamente e producano linee spettrali accurate.
