Kovats-index
De retentie-index van Kováts (meestal kortweg Kováts-index of retentie-index genoemd) is een begrip uit de gaschromatografie waarmee retentietijden omgezet kunnen worden in systeem-onafhankelijke getallen. Dit maakt het mogelijk gegevens onderling te vergelijken die afkomstig zijn van verschillende gaschromatografen, verschillende kolommen en andere laboratoria. Het principe werd ontwikkeld door de uit Hongarije afkomstige Zwitserse scheikundige Ervin Kováts, tijdens zijn onderzoek op het gebied van de etherische olieën. De index was, voordat de directe koppeling tussen de gaschromatograaf en de massaspectrometer gemeengoed werd, één van de belangrijkste manieren ter identificatie in de gaschromatografie.
