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.<\/p>\n
