Nanofibrous silica-based stationary phases ye electrospun Ultra-thin layer chromatography (E-UTLC) inotsanangurwa.Nanofibers dzakagadzirwa ne electrospinning mhinduro ye silica nanoparticles yakaparadzirwa mu polyvinylpyrrolidone mhinduro kugadzira composite silica/polymer nanofibers.Zvikamu zvekumira zvakagadzirwa kubva se-spun nanofibers, kana nanofibers dzakadziiswa kungave kuyambuka iyo polyvinylpyrrolidone kana kuti calcine uye kusarudza kubvisa iyo polymer.As-spun, crosslinked, uye calcined nanofibers ane mat makubvu akafanana (23-25 μm) akaongororwa sematanho akamira eE-UTLC kupatsanurwa kwelaser dhayi uye amino acids uye zvichienzaniswa nekutengesa silica TLC mahwendefa.As-spun nanofiber mahwendefa akapa kukurumidza mobile phase velocities, asi semamwe mapolymer-based nanofibers, kupatsanurwa kwaingoenderana nehunyanzvi hwekushandisa nosolvents yepolymer.Crosslinked nanofibers dzakanga dzisina kuganhurirwa maererano nekugadzikana kwemakemikari, asi kupatsanurwa kwakagadzira maumbirwo emuswe.Hapana lim itation maererano ne mobile phases, analyte solvents, uye maitiro ekuona akacherechedzwa kune calcined nanofibers.Kupatsanurwa kwakanyanya kweamino acids kwakaitwa mu 15 mm pa calcined nanofiber plates, ine hupamhi hweplate yakacherechedzwa yakaderera se8.6 μm, uye nhamba dzeplate dzakakura se 1400. Kuwedzera kurongeka kwema nanofibers kwakapa nguva pfupi yekuongorora asiwo yakakura nzvimbo yakafara.Kuwedzerwa kwematanho akamira kune silica-based nanofibers anowedzera zvakanyanya huwandu hwenharembozha, analyte solvents, uye maitiro ekuona ayo anogona kushandiswa E-UTLC kupatsanurwa.
