AB  - An ion chromatography method with non-suppressed conductivity detection was 
      developed for the simultaneous determination of dimethylamine (DMA), 
      trimethylamine (TMA) and trimethylamine-n-oxide (TMAO) in aquatic products. They 
      were separated by means of cation-exchange chromatography using a 3.0 mmol/L 
      methanesulfonic acid solution as eluent and an IonPac CS17 column (250 mm x 4 mm 
      i.d.) as the separation column. Detection limits of dimethylamine, trimethylamine 
      and trimethylamine-n-oxide were 0.06, 0.08 and 0.10 mg/L, respectively. The 
      relative standard deviations (RSDs) of peak area were less than 3.53%. The 
      recoveries were between 93.7% and 104.1%. Unlike traditional methods, this 
      validated method is inexpensive and stable.
