Glucaminium-based ionic kua yog ib chav kawm tshiab ntawm cov kua ionic uas nyuam qhuav tsim thiab npaj los ntawm kev ua haujlwm ntawm pawg amine ntawm N-methyl-d-glucamine, uas ua rau lawv zoo hydrophilicity vim muaj cov qauv ntawm cov piam thaj thiab them quaternary ammonium pawg.Nyob rau hauv txoj kev tshawb no, glucaminium-based ionic kua N, N-diallyl-N-methyl-d-glucaminium bromide tau ua ke thiab tom qab ntawd txuas rau saum npoo ntawm 3-mercaptopropyl hloov silica cov ntaub ntawv los ntawm "thiol-ene" nyem chemistry.Cov theem uas tau nyob ruaj ruaj yog tus cwj pwm los ntawm kev tsom xam thiab infrared spectroscopy, thiab tom qab ntawd ntim rau hauv HPLC kem.Kev sib xyaw ntawm tsib nucleosides tau siv los ua tus yam ntxwv ntawm kev sib cais ntawm cov kab tau txais nyob rau hauv HILIC hom thiab cov kab ke kev ua haujlwm tau txiav txim siab nrog cytidine raws li qhov ntsuas ntsuas, ncav cuag 80,000plates / m.Tom qab ntawd, tus cwj pwm tuav tau raug soj ntsuam los ntawm kev soj ntsuam cov txiaj ntsig ntawm ntau yam chromatographic yam ntawm kev tuav ntawm ntau hom kev daws teeb meem, thiab cov txiaj ntsig tau qhia tias qhov tsim tawm ntawm glucaminium-based ionic kua nyob ruaj khov theem tau nthuav tawm hydrophilic kev sib cuam tshuam / anion-pauv sib xyaw- hom kev tuav tswj mechanism.Thaum kawg, ob qhov sib xyaw ntawm nucleotides thiab flavonoids tau sib cais ntawm glucaminium-raws li ionic kua kem, raws li nyob rau hauv hydrophilic kev sib cuam tshuam thiab hydrophilic kev sib cuam tshuam / anion-pauv sib xyaw hom chromatography.Nyob rau hauv xaus, lub multimodal retention muaj peev xwm ntawm cov glucaminium-raws li ionic kua kem yuav muab ib tug ntau ntawm kev tuav tus cwj pwm thiab saj zawg zog xaiv rau polar thiab hydrophilic tebchaw.
