AB  - The method was specifically developed for the simultaneous determination of 
      streptomycin and dihydrostreptomycin residues in tomato paste by tandem dual 
      solid phase extraction (SPE) column cleanup-liquid chromatography-tandem mass 
      spectrometry. The residues were extracted from the samples with phosphate buffer 
      solution (pH 4). The cleanup was performed by the way of dispersive solid phase 
      extraction and tandem dual solid phase extraction column. The polar 
      chromatographic column was used to complete the separation of the analytes under 
      gradient elution and the analytes were detected in multiple reaction monitoring 
      (MRM) mode via positive electrospray ionization (ESI +). The external standard 
      calibration curves were used for the quantification. The linear ranges were from 
      0.01 to 0.2 mg/L with a good linear relationship (r > 0.999) for streptomycin and 
      dihydrostreptomycin. The limit of quantification (LOQs) was 0.02 mg/kg for the 
      both analytes. The recovery range was from 71% to 101% with the relative standard 
      deviations (RSDs) between 2.3% and 15%. It was indicated that this method is 
      accurate, easier, more sensitive, and has a better purification effect in the 
      monitoring and analysis. The method is accurate and specific to monitor and 
      analyze of streptomycin and dihydrostreptomycin residues in tomato paste and its 
      products.
