Ibicuruzwa

Nanofibrous silika ishingiye kumyanya ihagaze ya electrospun ultra-thin layer chromatografiya (E-UTLC) irasobanuwe.Nanofibers yakozwe na electrospinning igisubizo cya silika nanoparticles ikwirakwizwa mubisubizo bya polyvinylpyrrolidone kugirango ikore silika / polymer nanofibers.Ibyiciro bihagaze byakozwe kuva as-spun nanofibers, cyangwa nanofibers yashyutswe haba guhuza polyvinylpyrrolidone cyangwa kubara no guhitamo gukuramo polymer.As-spun, guhuza, hamwe no kubara nanofibers ifite uburebure bwa matel (23-25 ​​mm) byasuzumwe nkicyiciro gihagaze kuri E-UTLC itandukanya amarangi ya lazeri na acide amine kandi ugereranije nubucuruzi bwa silika TLC.Isahani ya nanofiber itanga umuvuduko wihuta wa mobile, ariko kimwe nizindi nanofibers zishingiye kuri polymer, gutandukana byari bihujwe gusa nubuhanga bukoresha nonsolvents ya polymer.Nanofibers ihujwe ntabwo yari igarukira mubijyanye no gutuza imiti, ariko gutandukana byabyaye imiterere yumurizo.Nta mbogamizi zijyanye n'ibice bigendanwa, isesengura rya analyte, hamwe na tekinoroji yo kureba byagaragaye kuri nanofibers yabazwe.Gutandukanya neza cyane aside amine byakorewe muri mm 15 kuri plaque ya nanofibre yabazwe, hamwe nuburebure bwa plaque bugera kuri 8,6 mm, hamwe nimero ya plaque ingana na 1400. Guhuza byongeye bya nanofibre byatanze igihe gito cyo gusesengura ariko nanone ubugari bunini bwahantu.Kwagura ibyiciro bihagaze kuri silika ishingiye kuri nanofibers yagura cyane urwego rwibyiciro bigendanwa, umusemburo wa analyte, hamwe nubuhanga bwo kubona amashusho bushobora gukoreshwa mugutandukanya E-UTLC.
