| titleOfInvention | Surface modification of resin chromatograph packing material and preparation method thereof and solid-phase extraction column |
| abstract | The present invention relates to a kind of surface modification of resin chromatograph packing material and preparation method thereof and fill the solid-phase extraction column of described chromatograph packing material.The SDVB polymer microballoon of high-crosslinking-degree is prepared by monomer styrene and cross-linker divinylbenzene, by substep key and mode, at SDVB polymer microballoon surface key and chloro-methyl group, then carry out quaterisation with triethylamine, obtain the surface modification of resin chromatograph packing material containing quaternary ammonium group.Chromatograph packing material preparation method in the present invention is simple, and it is strong and be prone to carry out the resin microsphere of surface modification to use specific crosslinker ratio to obtain stable performance, rigidity, uses chromatograph packing material of the present invention to fill the chromatographic column obtained and acid compound in solution in water environment is had the highest selectivity and sensitivity simultaneously. |
