Du sökte efter: Kromatografikolonn
Kromatografikolonner separerar molekyler under gas- eller vätskemetoder. Färdigpackade kolonner finns med olika stationärfaser och resiner. De färdigpackade kolonnerna står emot temperatur- och tryckvariationer som uppstår när mobilfasen trycks genom kolonnen. Det finns kromatografikolonner för preparativa och analytiska metoder för att separera komponenter baserad på individuell polaritet, sammansättning och storlek.
