ukubuka konke:
I-C8/SCX iyikholomu yokukhipha (C8/ SCX), eyakhiwe ngejeli ye-silica njenge-matrix C8 kanye nokupakishwa kwe-cation eqinile ye-SCX kuhlanganiswe nengxenye ethuthukisiwe, futhi ihlinzeka ngendlela yokugcinwa okukabili. Amaqembu asebenzayo e-C8 asebenzisana namaqembu e-hydrophobic we-analyte, kuyilapho i-SCX inokuxhumana ne-proton. Ngenxa yalokhu kusebenzisana okuqinile, izimo zokuguquguquka ezinamandla zingasetshenziswa ukuze kukhishwe okukhishwe okuvamile okungase kuphazamise ukutholwa kwe-UV noma kubangele ukucindezelwa kwe-ion ye-LC-MS. Akukho ukuvalwa kwesigaba sokumile, okungase kukhuphule ukusebenzisana phakathi kwesisekelo se-silyl alcohol esisele kanye ne-polar analyte, ngaleyo ndlela kusize ukuqinisa ukugcinwa.
imininingwane:
I-matrix: i-silika
Iqembu elisebenzayo: Octyl, Phenyl sulfonic acid
Indlela Yesenzo: Ukukhishwa kwesigaba sokuhlehla, ukushintshanisa okuqinile kwe-Cation
I-particle Usayizi: 40-75μm
Indawo engaphezulu: 510 m2 / g
Isicelo: Umhlabathi;Amanzi;Uketshezi lomzimba(i-plasma/umchamo njll.);Ukudla;Amafutha
Izicelo ezijwayelekile: Amaqembu asebenzayo e-C8 / SCX akhiwe nge-octyl ne-sulfonic acid esekelwe ku-ratio bond, enomsebenzi wokugcina okabili: i-octyl inikeza isenzo se-hydrophobic esimaphakathi, futhi isisekelo se-sulfonic acid sinikeza ukushintshaniswa kwe-cation okuqinile Uma kwenzeka ngokweqile. i-adsorption ye-C18 ne-C8, kanye nokugcinwa okuqinile kwe-SCX, ingasetshenziswa njengekholomu yokukhipha yemodi exubile ye-C8 / SCX

Ulwazi lwe-Sorbent
I-Matrix: I-Silica Functional Group: I-Octyl&Quaternary ammonium salt Indlela Yesenzo: Ukuhlehliswa kwesigaba sokukhishwa, ukushintshaniswa okunamandla kwe-anion Usayizi weNgxenye: 45-75μm Indawo engaphezulu: 510m2/g

Izicelo Ezijwayelekile
Amaqembu asebenzayo e-C8 / SAX akhiwe ngosawoti we-octyl kanye ne-quaternary ammonium, ahlanganiswe ngokulingana futhi anomsebenzi wokugcina kabili: i-octyl ihlinzeka ngokusebenza okuphakathi kwe-hydrophobic kanye ne-quaternary ammoniumihlinzeka ngokushintshaniswa okuqinile kwe-anion Uma kwenzeka i-adsorption eningi ye-C18 ne-C8, futhi ikhono lokugcinwa kwe-SAX liqine kakhulu, lingasetshenziswa njengekholomu yokukhipha yemodi exubile ye-C8 / SAX
