Smeltepunkts Standarder
Smeltepunktstandarder kalibrerer regelmæssigt analoge eller digitale apparater for at sikre pålidelige identitets- og renhedsbestemmelser. Termometer-, kapillarrør- eller varmeparametre kan opleve udstyrsfejl, der får faseændringsresultater til at ligge uden for acceptable grænser. Hvis smeltepunktet afviger fra referencesubstansens forudbestemte interval, indikerer fejlen, at apparatjusteringer er nødvendige. Anvendt i farmaceutiske sammenhænge fremmer smeltepunktstandarder ensartet lægemiddelproduktion for kundetilfredshed og overholdelse af myndighedskrav.
