vaaiga lautele:

Togafitiga muamua o le ammonium.It o se ituaiga o fesuiaiga cation vaivai, ituaiga fefiloi, vai ma infiltrating polymer adsorbent, mautu i le tele o ph 0 ~ 14.
O loʻo i ai i le WCX tulaga lelei uma o se HLB. Faʻaaogaina le WCX's stable and high selective solid-phase extraction method, e mafai ona mataʻituina, faʻamaonia ma faʻatusatusa le malosi o le alkaline e pei o le ammonium quaternary i faʻataʻitaʻiga matrix eseese.

fa'amatalaga:

Matrix: Polystyrene-Diethylbenzene polymer
Vaega Fa'atino: Carboxyl suia
Mechanism of Action: Ion exchange
Lapata'iga: 40-75μm
Lau'ele'ele: 600 m2/g
Ole Pore Tele:300Å
Malosiaga faafesuia'i ion:0.3meg/g
Fa'aoga: Eleele; Suavai; Suavai o le tino(plasma/urine etc.); Mea'ai
Fa'aoga masani: vaila'au fa'ama'i ma metabolites i mea'ai malie ma mea'ai, mata'ituina o vaila'au (e aofia ai su'esu'ega, fa'amaoniga fa'amaonia ma su'esu'ega fa'atatau), mea'ai fa'aopoopo ma mea fa'aleagaina, ma isi.
WCX e faʻavae i luga o le tele o le PS / DVB matrix, o le carboxyl modified hybrid cation exchange adsorbent, o le mama benzene e malosi le malosi o le hydrophobic, carboxyl e maua ai le vaivai o le fesuiaiga o le cation, talafeagai mo le faʻaogaina o mea vaivai cationic.
