Comparison of Different Reversed-Phase Packing Materials Based on Higher Organic Hybrid Particles

ABSTRACTAs part of our ongoing exploration into the field of hybrid organic/inorganic particles as HPLC packing materials, we have recently evaluated the use of porous particles synthesized from the co-condensation of ethylene-bridged alkoxysilanes with tetraethoxysilane [1,2]. By employing 4-100 mol% of hybrid organic/inorganic groups (i.e., O1.5SiCH2CH2SiO1.5) to 96-0 mol% inorganic groups (i.e., SiO2), novel hybrid particles have been prepared and shown to be excellent materials for the preparation of efficient and chemically resilient reversed-phase packing materials.
