Resumen
The present study presents a new analytical methodology for the determination of 11
compounds present in ethanol samples through the gas chromatography coupled to mass
spectrometry (GC-MS) technique using a medium polarity chromatography column composed
of 6% cyanopropyl-phenyl and 94% dimethyl polysiloxane. 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%.
