Ambient air - Determination of the concentration of levoglucosan - Chromatographic method

This document specifies a chromatographic method for the determination of levoglucosan in aqueous or organic extracts of filter samples collected in accordance with EN 12341:2023 [5]. The method has been tested for concentrations of ca. 10 ng/m3 up to ca. 3 000 ng/m3 with a sampling duration of 24 h. The procedure is also suitable for the determination of galactosan and mannosan.
Depending on the analysis instrumentation used, the carbohydrates inositol, glycerol, threitol/erythritol, xylitol, arabitol, sorbitol, mannitol, threalose, mannose, glucose, galactose and fructose can also be determined. However, no performance characteristics are given for these compounds in this document.

Außenluft - Bestimmung der Konzentration von Levoglucosan - Chromatographisches Verfahren

Dieses Dokument legt ein chromatographisches Verfahren zur Bestimmung von Levoglucosan in wässrigen oder organischen Extrakten von nach EN 12341:2023 [5] gesammelten Filterproben fest. Das Verfahren wurde für Konzentrationen von etwa 10 ng/m3 bis etwa 3 000 ng/m3 bei einer Probenahmedauer von 24 h geprüft. Das Verfahren ist auch zur Bestimmung von Galactosan und Mannosan geeignet.
Je nach verwendetem Analytikinstrumentarium können auch die Kohlenhydrate Inositol, Glycerol, Threitol/Erythritol, Xylitol, Arabitol, Sorbitol, Mannitol, Threalose, Mannose, Glucose, Galactose und Fructose bestimmt werden. In diesem Dokument werden jedoch keine Leistungskenngrößen für diese Verbindungen angegeben.

Air ambiant - Détermination de la concentration de lévoglucosan - Méthode chromatographique

Le présent document spécifie une méthode chromatographique pour la détermination du lévoglucosan dans des extraits aqueux ou organiques d’échantillons de filtres collectés conformément à l’EN 12341:2023 [5]. La méthode a été soumise à essai pour des concentrations d’environ 10 ng/m3 jusqu’à environ 3 000 ng/m3 avec une durée de prélèvement de 24 h. Le mode opératoire convient également pour la détermination du galactosan et du mannosan.
Selon les instruments d’analyse utilisés, il est également possible de déterminer les hydrates de carbone inositol, glycérol, thréitol/érythritol, xylitol, arabitol, sorbitol, mannitol, tréhalose, mannose, glucose, galactose et fructose. Cependant, le présent document ne spécifie aucune caractéristique de performance pour ces composés.

Zunanji zrak - Določanje koncentracije levoglukozana - Kromatografska metoda

Ta dokument določa kromatografsko metodo za določanje levoglukozana v vodnih ali organskih ekstraktih vzorcev filtrov, zbranih v skladu s standardom EN 12341:2023 [5]. Metoda je bila preskušena za koncentracije od pribl. 10 ng/m3 do pribl. 3000 ng/m3 z obdobjem vzorčenja 24 ur. Postopek je primeren tudi za določanje galaktozana in manozana.
Odvisno od uporabljenih instrumentov za analizo je mogoče določiti tudi ogljikove hidrate inozitol, glicerol, treitol/eritritol, ksilitol, arabitol, sorbitol, manitol, trealozo, manozo, glukozo, galaktozo in fruktozo. Vendar pa v tem dokumentu lastnosti delovanja za te spojine niso navedene.

Emissions from the combustion of biomass (e.g. wood firing) contribute to particulate air pollution (PM ,
PM ). Under inversion weather conditions in winter, the contribution of biomass combustion to the

particulate load can increase up to 50 % of the PM average daily value. As levoglucosan originates by
