Phospholipids were extracted using a mixture of chloroform and methanol followed by simple dilution of the lipid extract in methanol. Due to the instrumental fluctuations caused by the introduction of organic solvents, the use of internal standards (Te and Co) and naturally occurring molecular species (OH and N2 +) was evaluated for signal correction. Moreover, an external gas control module (EGCM) was applied to allow carbon decomposition and to minimize the matrix effects. The accuracy of the method was evaluated by comparing the obtained values with the results obtained by ion chromatography.  aMeat  aPhospholipids  aCarne  aFósforo  aFosfolipídios  aFração lipídica da carne  aLipid fraction of meat  aQuantification of phosphorus in meat lipid fractions1 aHIGUIERA, J.
