ʻO B&M C8/SCX ka kolamu unuhi (C8/ SCX), kahi i haku ʻia me ka silica gel e like me ka matrix C8 a me ka hoʻololi cation hoʻololi 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.

Hoʻohana maikaʻi ʻia i ka hoʻomaʻemaʻe ʻana i nā wai wai, mimi a me

ka alkalinity koko (cationic) a i ʻole nā ​​pūhui kūʻokoʻa e like me

nā lāʻau lapaʻau a me nā metabolites.

ʻO ka mea like me Agilent Bond Elut Certify

&Phenomenex Screen-C.

Hoʻokumu ʻia nā pūʻulu hana o C8 / SCX 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 adsorption nui o C18 a me C8, a me ka paʻa ikaika o SCX, hiki ke hoʻohana ʻia e like me ka
kolamu unuhi o C8 / SCX mode huikau
