This study aims to establish strategies for phosphorus determination in the lipid fraction of meat by the microwave induced plasma optical emission spectrometry (MIP OES) technique. 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. |
