In this work, the conventional reactions were used to functionalize the silica surface with amide and hydrocarbon chain groups affording two different mixed‐mode stationary phases (Sil‐amide‐C11 and Sil‐C12‐amide). The prepared stationary phases were analyzed by elemental analysis and thermogravimet...
