Schmelzpunkt-Standards
Schmelzpunktstandards kalibrieren regelmäßig analoge oder digitale Geräte, um zuverlässige Identitäts- und Reinheitsbestimmungen zu gewährleisten. Thermometer-, Kapillarröhrchen- oder Heizparameter können Gerätestörungen aufweisen, die dazu führen, dass Phasenwechselergebnisse außerhalb akzeptabler Grenzen liegen. Weicht der Schmelzpunkt vom vorbestimmten Bereich der Referenzsubstanz ab, weist der Fehler darauf hin, dass Geräteeinstellungen erforderlich sind. In der pharmazeutischen Industrie eingesetzt, fördern genormte Schmelzpunktstandards eine konsistente Arzneimittelherstellung zur Kundenzufriedenheit und zur Einhaltung behördlicher Vorschriften.
