| Abstract: | A method for the determination of citric acid in multi-matrix by liquid phase chromatography with liquid phase microextraction (LPME) as sample-preparation technique is introduced. The method integrates extraction, enrichment and clean-up into a single step. It is a very fast, effective and virtually "green" sample-preparation technique, which provided a good linear range (0.7 - 600 microg/mL) with r2 = 0.9995, a low detection limit (0.27 microg/mL, S/N = 3) and a satisfactory relative standard deviation (RSD < 5%). |
