Določanje hlapnih snovi v miniaturiziranih in pretočnih sistemih
diplomsko delo
Abstract
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.

| Secondary title: | Determination of volatile compounds in miniaturized and flow systems |
| Secondary abstract: | 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. |
