Colonne cromatografiche
Le colonne cromatografiche separano le molecole all’interno delle miscele durante metodi a gas o liquido. Riempite con fasi stazionarie o resine, le opzioni preconfezionate riducono il tempo di preparazione richiesto. I pezzi verticali sono in grado di resistere a temperature estreme e fluttuazioni di pressione quando la fase mobile viene forzata attraverso il mezzo. Soddisfa le procedure di laboratorio preparative e analitiche con le colonne cromatografiche per separare componenti mobili dissimili in base a polarità, composizione e dimensione.

Colonne HPLC per cromatografia preparativa Chromolith®
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.
