Separation of Benzyl Derivatives of Germanium for HPLC
2010
The paper presents interactions of mono-, di-, tri-, and tetrabenzyl derivatives of germanium with stationary phase surface and results from these processes of determination. As a final result of the work, optimal conditions of chromatographic separation and determination of these compounds by high-performance liquid chromatography (HPLC) method are proposed. During investigations, different types of stationary phase (including octadecyl, octyl, and chemically bonded aryl phases) and mobile phases are considered. As a result of the investigation, the highest selectivity is showed chemically by bonded aryl stationary phase combined with a mobile phase consisting of acetonitrile (capacity factors of di-, tri-, and tetrabenzyl derivatives of germanium k
