Conventional silica based HPLC stationary phases are usually bonded with mono-type alkyl chain molecules, e.g., C18, C8, etc. Recent studies have revealed that synergistic effects can be obtained when the bonded surface consists of C18 mixed with a shorter chain such as C8, amide or nitro-phenyl, etc. These new products offer different selectivity, coordinating multi-functionality, as well as a spacer effect (C18/C8).

Optimix C18/Amide

A mixed-phase of C18 and propionic amide provides unique selectivity which allows extremely polar and non-polar compounds to be analyzed in a single run under isocratic conditions. Metal Impurity<10ppm

Features:

• Unique selectivity
• Balanced retention for extremely polar and non-polar compounds
• Greater retention for polar compounds due to coordinating effects of C18 and amide
• Minimal tailing for basic compounds compared to any other type of columns, due to suppression of silanol effects by the amide group.
