Abstract

Avtomatizirani in miniaturizirani pretočni sistemi, med katere spada tudi laboratorij v brizgi, se vedno bolj uveljavljajo v sodobnih kemijskih laboratorijih. Zaradi svojih prednosti, kot so majhna poraba topil, reagentov, vzorcev ter zaradi tesnilnosti brizge, ki snovi ne prepušča, je ta tehnika dobra rešitev v smeri zelene kemije. V nalogi so opisane različne vrste sistemov za različne namene uporabe. Uporabljamo jo skupaj z drugimi kemijskimi tehnikami, ki zahtevajo predpripravo vzorca, ekstrakcijo ali separacijo faz. Zaenkrat se najbolj uporablja pri analizi okoljskih vzorcev, kjer določamo kovine v sledovih, amonijaka, radionukleotidnih elementov. Primerna pa je tudi za določanje estrov v biodizlu.

Secondary title: Analytical applications of lab-in-syringe
Secondary abstract: Automated and miniaturized flow systems, including lab-in-syringe are gaining ground in modern chemical laboratories. Due to its advantages, such as low consumption of solvents, reagents, samples due to the tightness of the syringe, which does not leak the substance, this technique is a good solution in the direction of green chemistry. The thesis describes different system settings for different purposes. It is used in conjunction with other chemical techniques that require extraction or separation phase prior to sample preparation. So far, it is mostly used in the analysis of environmental samples, where we determine the content of traces of metals, ammonia, radionuclide elements. It is also suitable for determining the concentration of esters in biodiesel.
