Pollen proteins in the atmosphere: a comparative study of three methods

In recent years, different methods and instruments have been used for the analysis of allergens in the atmosphere. The quantitative results have been very diverse, possibly due to the different efficiency of the instruments and/or the different sampling substrate, together with the difficulty of making comparisons between localities. The aim of this work was to compare three sampling systems to see which factors (extrinsic or in the apparatus itself) influence the quantification of airborne allergens.
