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.

Chromolith® WidePore (WP) 300 HPLC Columns for Bioapplications

Supplier: Merck

These columns have been designed following the high demand for suitable analytical methods for process monitoring and quality control of wide pore biomolecules. Accurate analysis of proteins, antibodies and large peptides requires columns with good permeability, along with better mass transfer and selectivity. In order for size exclusion not to influence the separation, the pore size should be approximately ten times larger than the molecule being analysed.
