As a result of the private burning of wood, concentrations of levoglucosan, mannosan, and galactosan in the air are usually increased during the winter months. On the other hand, one can expect a greater contribution of sugar components from biogenic sources during the summer months. An optimum separation and sensitivity of the saccharide markers that accumulate on air filters can be achieved on the Metrosep Carb 2 - 150/4.0 column with subsequent pulsed amperometric detection.
