Standard e reagenti per la spettroscopia
Gli standard di spettroscopia sono materiali di riferimento critici utilizzati per determinazioni spettroscopiche accurate e affidabili. Questa categoria include una varietà di standard essenziali per diverse tecniche spettroscopiche, come gli standard di assorbimento atomico e gli standard di emissione atomica, che sono vitali per la misurazione precisa delle concentrazioni di metalli. Inoltre, la categoria comprende standard per la risonanza di spin, cruciali per la spettroscopia di risonanza di spin elettronico (ESR) e la spettroscopia di risonanza magnetica nucleare (NMR), garantendo una calibrazione e una validazione precise di questi strumenti. Sono inclusi anche gli standard di spettrofotometria, che forniscono punti di riferimento per l'analisi quantitativa dell'assorbimento della luce in vari campioni. Questi standard svolgono un ruolo fondamentale nel garantire l'accuratezza, la coerenza e la riproducibilità delle misurazioni spettroscopiche in numerose applicazioni scientifiche e industriali, tra cui l'analisi ambientale, i test farmaceutici e la ricerca sui materiali. Fornendo materiali di riferimento ad alta purezza, gli standard di spettroscopia supportano lo sviluppo di metodi analitici affidabili e il mantenimento di rigorosi protocolli di controllo della qualità.
