    Determination of metformin in biological fluids
        (human plasma, urine, etc)
  Challenge to conventional chromatographic methods 
         Metformin
         •   Oral antidiabetic drug
         •   Small molecule with high polarity
         (impossible to maintain by RP columns)
         •   pKa1=2.8 and pKa2=11.5
                               Determination of Metformin in urine
                 There are many methods to determine Metformin in urine :
                 •  Capillary electrophoresis (with contactless conductivity 
                    dedection)
                 •  Voltammetric method
                 •  Cation-exchange HPLC 
                 •  Normal phase chromatography
                 •  LC-MS
                 •  RP-HPLC (specific column or common columns using ion-
                    pairing agent)
          The purpose of the study
     To developed a method using a conventional column
        Ion-pairing chromatography
