dc.description.abstractThis work provides a short and easy protocol that allows the analysis of both methanol and ethanol in the static headspace of olive oil. The procedure avoids any kind of sample pre-treatment beyond that of heating the oil to allow a maximum volatile concentration in the headspace of the vials. The method's LOD is 0.55 mg kg¿1 and its LOQ is 0.59 mg kg¿1. Advantages of this method are: ¿Simultaneous determination of methanol and ethanol (the pre-existing Spanish specification UNE-EN 14110 only analyses methanol). ¿No need of equipment modifications (standard split injectors work perfectly). Use of a highly polar capillary GC column, leading in most cases to chromatograms in which only three dominant peaks are present ¿ methanol, ethanol, and propanol (that is extremely positive for easy interpretation of results). ¿Use of an internal standard (1-propanol) to determine the concentration of the analytes, reducing the presence of error sources.-
