Results of an interlaboratory comparison of analytical methods for quantification of anhydrosugars and biosugarsin atmospheric aerosol

An interlaboratory comparison was performed to evaluate the analytical methods for quantification of anhydrosugars - levoglucosan, mannosan, galactosan - and biosugars - arabitol, glucose and mannitol - in atmospheric aerosol. The performance of 10 laboratories in Italy currently involved in such analyses was investigated on twenty-six PM (particulate matter)ambient filters, three synthetic PM filters and three aqueous standard solutions
