HxSil C8
Silica packing material for a variety of reversed-phase separations
Hamilton HxSil C8 columns are well end-capped for retention time reproducibility and durability. The C8 demonstrates excellent selectivity needed for complex sample mixtures and gives shorter retention times than a C18.
Application Examples: Polycyclic aromatic hydrocarbons, small organic molecules.

Overview of HxSil C18
Alkylated silica is used for reversed-phase HPLC columns. Hamilton offers two varieties of this composition: C18 and C8. C18 columns are more hydrophobic than C8 columns and thereby retain hydrophobic analytes more strongly than a C8 column will. Due to stronger retention, C18 columns tend to result in longer retention times and better separations. C8 columns result in shorter analyte retention times which produce faster analysis times.

HPLC Guard Columns, HPLC Guard Cartridges
HPLC guard columns and guard cartridges protect analytical, semi-prep and preparative HPLC columns. They help by removing particulate contaminants and highly absorptive compounds from samples, prolonging column life.
Work with R&D engineers to customize Hamilton parts
Hamilton's "Custom Built" program puts you directly in contact with a Hamilton R&D Engineer to discuss your application and product needs. The engineer will point you to a standard solution or propose a customized solution to meet your needs.
