The validation parameters were determined according to NBR ISO 17025:2005. The recovery rates of the studied compounds were 100.4% to 114.7%. The limits of quantification are between 2.4 mg.kg-1 and 5.8 mg.kg-1. The uncertainty of the measurement was estimate in circa of 8%.openAccessmass spectroscopyethanolbioethanolvolatilityorganic compoundsgas chromatographymetrologyArtigo de periódico97510.1088/1742-6596/975/1/012015https://orcid.org/0000-0002-6745-8185Sem Percentil16.00
