You searched for: 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.

Avantor® Prevail C8, HPLC Columns
Supplier: Avantor
Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.
