vaaiga lautele:

O le C18Q (hydrophilic) o se koluma silica gel fa'aliliuina vaega C18 fa'atasi ma fa'amautu lelei. E mafai ona fa'aogaina le vai mama e pei o le telefoni feavea'i, ma e mafai ona tu'u'ese'ese ai fa'ama'i, fa'aitutū ma fa'avae fa'aola, fa'apea fo'i ma le tele o vaila'au ma peptide.

E tutusa ma le pupuni C18, e masani ona faʻaaogaina e faʻamamā ai, aveese ma faʻapipiʻi mea filogia i vai faʻataʻitaʻiga o le siosiomaga, e pei ole polycyclic aromatic hydrocarbons, vailaau faʻasaina i meaʻai ma meainu, ma vailaʻau ma metabolites i sua ola. E mafai fo'i ona fa'aoga e fa'amamā ai vaifofo a'o le'i fa'afesuia'i ion. I fa'aoga fa'aola e pei o peptide, o le fa'atinoina o le fa'aaogaina o DNA e sili atu nai lo le C18 masani.
Ole koluma e tutusa ma Aglient Accu Bond C18, Bond Elute C18 OH.
