HPLC-kolonner, præparativ skala, Chromolith® Prep

Supplier: Merck

Chromolith® Prep monolitiske stationære faser er nye ultrarene silicafaser, som får deres specielle egenskaber fra en bimodal porestruktur. Strukturen er en egenskab ved den nye 'Sol-Gel'-teknologi, og den består af makroporer og mesoporer. Mesoporerne med en gennemsnitlig diameter på 12 nm, former den fine porøse struktur i kolonnens indre og danner et meget stort overflade areal, hvorpå adsorption af målstofferne optræder.
