- Abstract
-
This deliverable specifies a chromatographic method for the determination of levoglucosan in aqueous or organic extracts of filter samples collected in accordance with EN 12341:2014. The method has been tested for concentrations of approx. 10 ng/m3 up to approx. 3000 ng/m3 with a sampling duration of 24 hours. 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. The responsible national standardisation committee is the working committee 134-04-02-01UA ‘Measurement of organic compounds (I) (VOC, PAH)´ in the DIN Standards Committee VDI/DIN Commission on Air Pollution Prevention (KRdL).
