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.

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.
