Standard per punto di fusione
Gli standard di punto di fusione calibrano regolarmente gli apparecchi analogici o digitali per garantire determinazioni affidabili di identità e purezza. I parametri del termometro, del capillare o del riscaldatore possono subire guasti che portano i risultati dei cambiamenti di fase al di fuori dei limiti accettabili. Se il punto di fusione differisce dall’intervallo predeterminato della sostanza di riferimento, l’errore indica che sono necessarie regolazioni dell’apparecchiatura. Utilizzati in ambito farmaceutico, gli standard di punto di fusione favoriscono una produzione coerente dei farmaci per la soddisfazione dei consumatori e il rispetto delle normative.
