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.

ChiraDex®

Supplier: Merck

ChiraDex® is a versatile HPLC column characterised by broad enantioselectivity and can be used for the separation of enantiomers of numerous different classes of substances. ChiraDex® is based on beta-cyclodextrin covalently linked to spherical particles of silica, and is ideal for chiral separation of hydrocarbons, steroids, phenol esters and derivatives, aromatic amines, heterocycles with five- to seven-membered ring. Simply composed RP-eluents can be used in most separations.
