20.500.12556/RUL-129727 Določanje hlapnih snovi v miniaturiziranih in pretočnih sistemih Determination of volatile compounds in miniaturized and flow systems Miniaturizirani in pretočni sistemi, med katere spadajo laboratoriji na čipu in na papirju, se veliko uporabljajo v diagnostiki, okoljski analizi in pri nadzoru hrane. Njihova prednost pred klasičnimi analitskimi tehnikami je predvsem njihova majhnost, ki omogoča analizo na mestu vzorčenja, enostavna prenosljivost in shranjevanje. Hkrati zahtevajo majhno količino reagentov in vzorca. Analize so večinoma preprostejše in hitrejše za izvedbo, njihova izdelava pa je relativno preprosta in cenovno ugodna. V analizni kemiji mikrofluidni sistemi omogočajo določanje nekaterih hlapnih snovi. Določitev temelji na specifični reakciji analita v raztopini ali na manj specifični reakciji, kjer najprej poteče ločba analita od same matrice. V diplomski nalogi sem se osredotočila na nekatere konkretne primere določitev amonijaka, cianida, formaldehida in etanola ter jih tudi opisala in primerjala. Miniaturized and flow systems, including lab-on-a-chip and micro paper-based analytical device, are mainly used in diagnostics, environmental monitoring and food control. One of their advantages, in contrast to conventional analytical techniques, is their small size. It enables on-site analysis, simple transportation and storage. Other advantages are also their low reagent and sample consumption, less complex analysis, relatively low cost and simple fabrication. In analytical chemistry microfluidic devices enable determination of some volatile compounds. The quantification is based on specific reaction of analyte in the sample solution or less specific reaction of previously separated analyte from the matrix. In my undergraduate thesis I focused on some specific examples of determination of ammonia, cyanide, formaldehyde and ethanol. I also described and compared these examples. hlapne spojine laboratorij na čipu laboratorij na papirju volatile compounds lab-on-a-chip micro paper-based analytical device true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-09-07 12:30:04 2021-09-07 12:30:06 2022-09-09 04:12:59 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 16881 79155459 Sadl_Sara_-_Dolocanje_hlapnih_snovi_v_miniaturiziranih_in_pretocnih_sistemih.pdf Sadl_Sara_-_Dolocanje_hlapnih_snovi_v_miniaturiziranih_in_pretocnih_sistemih.pdf 1 015C2239CA2A68D186975FF7210408C9 6945ebc69b5004065946b265d9a01842a400927a21f95ff2fc43a0da549ae422 5348fb74-0fc6-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146752 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
