Silica Packings

HPLC Single Group Blur

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.
