Abstract

Onesnažena atmosfera v prostorih, kjer so shranjeni zgodovinski predmeti, lahko predstavlja velik problem, če ti niso prezračevani in je v njih prisotna visoka koncentracija onesnaževal, med katerimi so lahko tudi kisline, kot sta metanojska in etanojska kislina. Njihovo vsebnost lahko določimo tako, da jih najprej vzorčimo s pasivnimi vzorčevalniki. Delimo jih lahko glede na obliko: cevasti in ploščati ter glede na vrsto pregrade: na difuzijske in tiste s polprepustno membrano. Vzorčenju sledi analiza z instrumentalnimi tehnikami. Najpogosteje se uporabljajo separacijske tehnike, kot so plinska, tekočinska ali ionska kromatografija.

Secondary title: Passive samplig of methanoic and ethanoic acid from air
Secondary abstract: Places that contain historical objects can suffer from a polluted interior atmosphere when they are not properly aired. These pollutants come in many forms, acids (such as methanoic and ethanoic acid) being one of them. The concentration of these acid atmospheric pollutants can be determined with passive samplers. According to their shape, these samplers can be divided into tube and badge samplers, while both of these types also come in diffusive and semi-permeable variants. Samples from these devices are analysed using instrumental techniques. To that end, separation techniques like gas, liquid, and ion chromatography are used most often.
