Standaarden voor smeltpuntbepaling
Smeltpuntstandaarden kalibreren regelmatig analoge of digitale apparaten om betrouwbare bepalingen van identiteit en zuiverheid te garanderen. Parameters van thermometers, capillaire buisjes of verwarmers kunnen defect raken, waardoor de faseovergangsresultaten buiten de aanvaardbare grenzen vallen. Wanneer het smeltpunt afwijkt van het vooraf bepaalde bereik van de referentiestof, geeft de fout aan dat aanpassingen aan de apparatuur nodig zijn. Gebruikt in de farmaceutische industrie bevorderen smeltpuntstandaarden een consistente geneesmiddelenproductie voor consumententevredenheid en naleving van voorschriften.
