SiliaChrom XDB C18

by SiliCYCLE

SiliaChrom® Narrow Bore HPLC Columns XDB C18

SiliaChrom - XDB C18 and C8 are specially designed to present high pore size and low surface area for the separation of large hydrophobic molecules. The relatively low surface area allows a shorter retention time for that kind of compounds. SiliaChrom XDB C18 and C8 present the lowest carbon loading of  all SiliaChrom HPLC series. SiliaChrom XDB phases are ideal for separation of barbiturates, fat-soluble vitamins, fatty acids and steroïds.

SiliaChrom® XDB C18 presents the same bonded phase as the SiliaChrom XDB 1 C18 and XDB1 C18-300. The pore size of the silica support is intermediate, 150 Å, which allows to separate larger molecules than its 100 Å equivalent. The lower surface associated allows compounds to have shorter retention times. SiliaChrom XDB C18 is an excellent equivalent to Hypersil BDS-C18 and Zorbax XDB-C18.
