| Zusammenfassung |
| The determination of atmospheric concentrations of levoglucosan and its two
isomers, unambiguous tracers of biomass burning emissions, became even more
important with the development of wood as renewable energy for domestic
heating. Many researches demonstrated the increase during recent years of
atmospheric particulate matter load due to domestic biomass combustion in
developed countries. Analysis of biomass burning tracers is traditionally
performed with Gas Chromatography-Mass Spectrometry (GC-MS) technique after
derivatization and requires an organic solvent extraction. A simpler and
faster technique using Liquid Chromatography – Electrospray Ionisation –
tandem Mass Spectrometry (LC-ESI-MS/MS) was optimized for the analysis of
levoglucosan, mannosan and galactosan isomers after an aqueous extraction.
This technique allows a good separation between the three compounds in a
very reduced time (runtime ~5 min). LOD and LOQ of this method are 30 μg l−1
and 100 μg l−1 respectively, allowing the use of
filters from low-volume sampler (as commonly used in routine campaigns). A
comparison of simultaneous levoglucosan measurements by GC-MS and
LC-ESI-MS/MS for about 50 samples coming from different types of sampling
sites and seasons was realized and shows very good agreement between the two
methods. Therefore LC-ESI-MS/MS method can be used as an alternative to
GC-MS particularly for measurement campaigns in routine where analysis time
is important and detection limit is reduced. This paper shows that this
method is also applicable to other environmental sample types like soil. |
