| Abstract: | An improved high-performance anion-exchange chromatography (HPAEC) with pulsed amperometric detection (PAD) method is developed and validated for simultaneous determination of atmospherically relevant sugar alcohols, monosaccharides, and monosaccharide anhydrides. The improved method enables the separation of levoglucosan and arabitol which were not or insufficiently separated by the previous HPAEC–PAD methods. Reproducibility of the method was tested for both standard solutions and atmospheric aerosol samples. The peak area relative standard deviation (RSD%) of standard solutions were found to be lower than 1.5% for consecutive analyses (n = 3) and lower than 4% for day to day variation (n = 9). The peak area RSD% of atmospheric samples with typical European wintertime monosaccharide concentrations (n = 9) was found to be similar to that of standard solutions. Limits of detection ranged from 0.002 mg L?1 for inositol to 0.08 mg L?1 for fructose. The developed method offers a simple, reliable and cost effective determination of atmospheric tracers for biomass combustion and for selected bio-aerosol components at sub-nanogram per cubic-meter-air concentration levels for routine analysis. |
