Gel di silice, Pore size: 60 Å ≥99.99%, spherical 10 µm APS for preparative chromatography

Supplier: Merck

Le fasi stazionarie in silice monolitica Chromolith® Prep sono costituite da silice ultrapura, che derivano le loro speciali proprietà da una struttura bimodale della silice. Questa struttura è caratteristica di una nuova tecnologia 'Sol-Gel' ed è costituita da macropori e mesopori. I mesopori, con un diametro medio di 12 nm, formano la struttura porosa fine all'interno della colonna e crea un'area superficiale molto ampia su cui si verifica l'assorbimento dei composti.
