ʻike nui:

ʻO C8/SCX ka kolamu unuhi (C8/ SCX), i haku ʻia me ka silica gel e like me ka matrix C8 a me ka hoʻololi ʻana i ka cation ikaika SCX packing i hui pū ʻia me ka ʻāpana i hoʻopaʻa ʻia, a hāʻawi i ka mīkini paʻa pālua. Hoʻopili nā hui hana C8 me nā pūʻulu hydrophobic o ka analyte, aʻo ka SCX he pilina me ka proton. Ma muli o kēia mau pilina ikaika, hiki ke hoʻohana ʻia nā ʻano hoʻoheheʻe ʻoi aku ka ikaika no ka wehe ʻana i nā unuhi maʻamau i hiki ke keʻakeʻa i ka ʻike ʻana o UV a i ʻole ka hoʻopau ʻana i ka ion LC-MS. ʻAʻohe pani o ka manawa paʻa, hiki ke hoʻonui i ka pilina ma waena o ke koena silyl alcohol base a me ka polar analyte, pēlā e kōkua ai i ka hoʻonui ʻana i ka paʻa.

kikoʻī:

Matrix: Silika
Pūʻulu hana: Octyl，Phenyl sulfonic acid
Mechanism of Action: Reverse phase extraction, hoʻololi Cation ikaika
Laki ʻāpana: 40-75μm
Ili: 510 m2 /g
Noi: Ka lepo; Ka wai; Nā wai o ke kino (plasma/mimi etc.); ʻAi; ʻAila
Nā noi maʻamau: ʻO nā pūʻulu hana o C8 / SCX ua haku ʻia me ka octyl a me ka sulfonic acid e pili ana i ka ratio bond, nona ka hana paʻa ʻelua: hāʻawi ka octyl i ka hana hydrophobic medium, a hāʻawi ka base acid sulfonic i ka hoʻololi cation ikaika I ka hihia o ka excessive. adsorption o C18 a me C8, a me ka paʻa ikaika o SCX, hiki ke hoʻohana ʻia e like me ke kolamu unuhi o C8 / SCX ʻano hui ʻia.
