C8/SCX (octyl/sulfonic acid SPE ikholamu)
Isishwankathelo:
I-C8 / SCX yikholomu yokukhutshwa (i-C8 / SCX), equlunqwe ngejeli ye-silica njenge-matrix C8 kunye ne-cation exchange eyomeleleyo ye-SCX yokupakisha ngokudibanisa nomlinganiselo ophuculweyo, kwaye ibonelela ngeendlela zokugcinwa kwezinto ezimbini. Amaqela asebenzayo e-C8 asebenzisana namaqela e-hydrophobic e-analyte, ngelixa i-SCX inentsebenziswano kunye neproton. Ngenxa yolu nxibelelwano lunamandla, iimeko zokugungxula ezinamandla zingasetyenziselwa ukususa izicatshulwa eziqhelekileyo ezinokuphazamisa ukubhaqwa kwe-UV okanye kubangele ukunyanzeliswa kwe-ion ye-LC-MS. Akukho kuvalwa kwenqanaba lokumisa, elinokwandisa intsebenziswano phakathi kwesiseko sotywala se-silyl esishiyekileyo kunye ne-polar analyte, ngaloo ndlela inceda ukukhulisa ugcino.
iinkcukacha:
Matrix: Silika
Iqela eliSebenzayo: Octyl, Phenyl sulfonic acid
Indlela yokuSebenza: ukutsalwa kwesigaba esibuyiselwe umva, utshintshiselwano olunamandla lweCation
Ubungakanani besuntswana: 40-75μm
Ummandla oMphezulu: 510 m2 /g
Ukusetyenziswa: Umhlaba;Amanzi;ulwelo lomzimba(iplasma/umchamo njalo njalo);Ukutya;Ioyile
Izicelo eziqhelekileyo: Amaqela asebenzayo e-C8 / SCX aqulunqwe nge-octyl kunye ne-sulfonic acid esekelwe kwi-bond bond, enomsebenzi wokugcinwa kabini: i-octyl ibonelela ngesenzo se-hydrophobic esiphakathi, kunye nesiseko se-sulfonic acid sibonelela ngokutshintshiselana kwe-cation eqinile Kwimeko yokugqithisa kakhulu. I-adsorption ye-C18 kunye ne-C8, kunye nokugcinwa okunamandla kwe-SCX, ingasetyenziselwa njengekholamu yokukhutshwa kwe-C8 / SCX imo edibeneyo.

Ulwazi lweSorbent
I-Matrix: Iqela leSilica eliSebenzayo: ityuwa ye-Octyl&Quaternary ammonium ityuwa Indlela yokuSebenza: ukutsalwa kwesigaba esibuyiselwe umva, utshintshiselwano olunamandla lweanion Ubungakanani beNcam: 45-75μm Indawo engaphezulu: 510m2/g

Usetyenziso oluqhelekileyo
Amaqela asebenzayo e-C8 / SAX aqulunqwe nge-octyl kunye ne-quaternary ammonium salts, edityaniswe ngokulinganayo kwaye inomsebenzi wokugcinwa kabini: i-octyl ibonelela nge-medium hydrophobic function kunye ne-quaternary ammonium ibonelela ngokutshintshiselana okunamandla kwe-anion Kwimeko ye-adsorption ephezulu ye-C18 kunye ne-C8, kwaye amandla okugcinwa kwe-SAX ukuba yomelele kakhulu, inokusetyenziswa njengekholamu yokukhutshwa kweC8 / Imodi edibeneyo ye-SAX
