AB  - A flow-through optosensor is here proposed for the determination of mixtures of 
      two widely used pesticides, carbendazim and o-phenylphenol, in fruits. The 
      pesticides are separated on-line using an additional amount of solid support, C18 
      silica gel, in the flow-through cell. The resolution is performed due to the 
      different retention/desorption kinetics of the analytes when interacting with the 
      C18 microbeads. Therefore, both separation and determination are integrated in 
      the same cell, considerably simplifying the system. In addition, the use of 
      Sequential Injection Analysis provides a high degree of automation and minimum 
      wastes generation. After the analytes are separated, their native fluorescence is 
      measured, obtaining linearity in the 2.0-30 and 1.1-20 mg kg(-1) ranges for 
      carbendazim and o-phenylphenol. The detection limits are 0.60 and 0.33 mg kg(-1) 
      for carbendazim and o-phenylphenol respectively. The proposed method fulfills the 
      maximum residue limits (MRLs) established in Europe and USA for these pesticides 
      in cherries, pineapple, and mango: 5-10 mg kg(-1). In order to demonstrate the 
      suitability of the method, several samples have been analyzed and the obtained 
      results compared with a chromatographic method.
