Resumo

IN MINERAL DIESEL FUEL USING SELECTIVE ION MONITORING.The selective ion monitoring acquisition mode in mass spectrometry was applied to identify, in the diesel complex matrix, the raw materials (vegetable oil and alcohol) that originate biodiesel.Biodiesel samples obtained from babassu, castor, palm and soybean vegetable oils and pure fatty acid methyl and ethyl esters were used to develop this method, using specific fragments in mass spectrometry and the "window system" in gas chromatography.The commercial Brazilian B2 samples were found to be produced with soybean oil, transesterified with methanol.
