| titleOfInvention | Carbamic acid ester type liquid phase chromatogram stationary phase and preparation method thereof |
| abstract | The invention relates to an efficient liquid phase chromatogram stationary phase which is characterized in that gel in the structure is a particle with hydroxyl, R1 is methyl or ethyl, m is equal to 3-8 and n is equal to 3-29. The liquid phase chromatogram stationary phase has the following advantages: 1, the structure is novel, a polar carbamic acid ester structure is embedded in a hydrophobic carbon chain, wherein an alkyl is at the tail end of an ester bond of the carbamic acid ester (O-alkyl), so that the effect of silicon hydroxyl on the surface of filler on separation can be benefited to being eliminated due to the principle of electrostatic screening, and the compatibility of chromatograph filler and pure water moving phase can be improved; 2, the preparation process for the stationary phase is simple and reliable, and the raw material is easy to obtain, thus being beneficial to batch production of the stationary phase; and 3, the liquid phase chromatogram stationary phase has wide application range. The stationary phase is a pervasive reversed phase chromatography stationary phase, has good analysis property to most polar and nonpolar compound, and has good market application prospect. The invention discloses a preparation method thereof. |
