Concentrations of formaldehyde and acetaldehyde were respectively analysed in forty-five alcoholic beverages obtained from the market. After derivatization with PFBHA, GC-ECD and GC-MSD were employed for analysis. The peak area of aldehyde oximes (derivatives with PFBHA) increased with the increasing ethanol content (5%, 10%, 15%, 20% and 40%). When three-point calibration curves for the selected ethanol concentration (5, 13, 21 and 40%, v/v) were studied, suitable linearity against ethanol concentration was observed only under 5, 13, and 21% (ethanol, v/v).
