An improved stationary phase composition in chromatography and a method for producing the same. The composition has excellent batch-to-batch reproducibility, is stable under basic and acidic elution conditions, has a low silanol content, and does not show tailing in basic samples. The formula R 1 δ- Q α- (CH 2 ) β SiR 2 γ X 3-γ A stationary phase is obtained by modifying an inorganic substrate with at least one silane represented by the formula: [Selection] Figure 2 |
