The method uses a 4 ?L sample of bio-oil in a headspace vial (ca. 20 mL). Complete evaporation of the compounds was achieved after seven minutes at 90 °C. The method showed good precision and accuracy for methanol, ethanol, acetone and acetic acid. The recovery of furfural was low (74.3%). The results showed that the protocol can be applied for the determination of methanol, ethanol, acetone and acetic acid in bio-oil. Detection limits ranged from 0.13 to 0.16 ?g. Acetic acid was the dominant analyte in the heavy bio-oil and light bio-oil analysis (113. 3 and 85.1 ?g mg?1, respectively), followed by methanol, ethanol, and acetone. The polymerisation of furfural was suspected as the cause of its poor quantification.  aBiofuels  aBiomass  aEucalyptus  aWood  aBiocombustível  aBiomassa  aEucalipto  aMadeira  aFID1 aLOPES, A.
